MatrixSSL 1.8.3

API changes

• ‘const’ qualifiers added to literal string parameters for matrixRsaReadPrivKey, matrixRsaReadKeys, matrixRsaReadKeysEx and matrixX509ReadPubKey.

• Additional error reporting in RSA public decryption routine.

• Improved the enforcement of maximum certificate chain length.
• Added the –fPIC compile option to default POSIX builds.
• Fixed one time memory leak on error conditional during certificate parsing.
• 2007 copyright update.

MatrixSSL 1.8.2

API additions

• None

• New "leaky bucket" algorithm for empty message denial-of-service countermeasure. Previously, the count of empty messages was continually being incremented by the MatrixSSL library regardless of any interleaving valid messages. This could potentially cause the connection to be closed if a peer was sending many blank SSL messages. The count will now decrement on valid messages. This change is most relevant to use-cases that involve an OpenSSL client communicating with a MatrixSSL server, as these clients tend to periodically send a blank record.

• None

MatrixSSL 1.8.1

API additions

• None

• Cleaner POSIX cross platform compiles for newer versions of Linux.
• Build support for Intel Macs (tested on OS X 10.4 CoreDuo).

• Minor compile warnings fixed.
• Graceful handling when MAX_CHAIN_LEN limit is exceeded in certificate parsing.
• Added ASN.1 BMPSTRING format support to certificate parsing.
• Fixed matrixSslReadKeysMem so that private key parameter is optional.
• Fixed one time memory leak for client initialization issues that include non-parsable certificates.

MatrixSSL 1.8

API additions

• Addition of two new server APIs that allow the user to add a custom flag value to client sessions. Servers may now assign persistant custom data to connected sessions that can be later retrieved from a session that was established with a session resumption handshake. See the API documentation for matrixSslSetResumptionFlag and matrixSslGetResumptionFlag for more details.

• Ability to put multiple certificates in a single PEM file.
• The handshake will now fail on an un-authenticated cert if no user validation callback has been defined with matrixSslSetCertValidator. It is still encouraged that a callback be registered.
• Users can now reply to a closure alert with a closure alert of their own using matrixSslEncodeClosureAlert. Previously, the SSL_CLOSED flag prevented this. Now only error cases will prevent the closure alert from being created.

• Numerous compile warnings fixed. Especially in the area of unsigned char / char type mismatches.
• Added explicit ‘void’ types to empty parameter functions.
• Fixed a bad shift operation in cipherSuite.c (no functional change).
• Fixed possible memory leak of pre-master secret if deleteSession called on some corner failure cases.
• Fixed compile and link issues when USE_FILE_SYSTEM was turned off in matrixConfig.h.
• Fix for unknown X.509 certificate extension parsing in which the extensions did not provide explicit data lengths in the encoding.
• Fixed parse issue with an empty AuthorityKeyIdentifier certificate extension.
• Created new sample certificates with updated dates.

MatrixSSL 1.7.3

Bug fixes and optimizations

• Fixed issue with certificate extension parsing causing a cert with some unrecognized extensions to fail validation.
• Fixed requirement when USE_CLIENT_SIDE is enabled with ReadKeysMem - CA is no longer required.

MatrixSSL 1.7.1b

Bug fixes and optimizations

• Fixed packaging issue causing a build error on Windows and Linux. No functional change from 1.7.1

MatrixSSL 1.7.1

Bug fixes and optimizations

• Fixed certificate chain parsing bug where a valid certificate chain was marked as invalid under certain circumstances. The result of the fix is that more cert chain configurations are supported.
• Added support for cert validation when the server sends the Root CA cert in addition to the lower levels of the chain. Typically the Root CA cert is loaded into the client, and not sent by the server. We have encountered some deployments where the server does send the root CA as well, and now successfully validate this chain.
• Relaxed parsing of the CertificateSerialNumber field within AuthorityKeyIdentifier. Although officially defined as an ASN.1 INTEGER type, some certificate generators use a non-integer value. Parser now supports these technically incorrect datatypes.

MatrixSSL 1.7

Overall changes

• Explicit support for anonymous RSA handshaking
• New APIs to support anonymous handshaking and re-handshaking over existing connections with new key material

• Version updated from 1.2.5 to 1.7 to mirror commercial MatrixSSL versioning
• Directory and file reorganization

• Significantly accelerated RSA handshake speeds
• Additional parsing of X.509 certificate extensions

MatrixSSL 1.2.5

Overall changes

• No API changes from 1.2.4 release

• Updated expiration date in sample certificates

• Remove unnecessary link to -lcrypto on Linux
• Fix prevTicks compatibility on non-i386 Linux platforms

MatrixSSL 1.2.4

Overall changes

• No API changes from 1.2.2 release
• There was no public 1.2.3 release

• Client will reply with NULL cert message if client authentication is requested.

• Generate static libraries in addition to shared objects on Linux
• AMD64/Nacona x64 compile support on Linux
• Changed all instances of int types to int32 to be more explicit and to allow easy global redefinitions for porting
• Corrected the maximum message size limit to match the SSL specification
• Cert parse can handle duplicate distinguished name entries.
• ASN.1 parse fix for AlgorithmIdentifier missing the trailing NULL
• Checking certificate version before doing checking the 'ca' member of the basic constraint entry during certificate validation.
• Developers may notice some internal routines using a psPool_t parameter. These parameters allow deterministic memory support in the commercial version of MatrixSSL. They are unused in the GNU version of MatrixSSL.

MatrixSSL 1.2.2

Functional changes

• Added legacy certificate support

- for certificates without basic constraints
- MD2 support for older certificates (Because it is a less secure algorithm, it must be explicitly enabled).

• Sanity check against invalid key lengths from certificate (potential DOS fix)
• Fixed 64 bit issue with mpi.c
• Fix potential leak in certificates with duplicate fields
• Allow application data parsing within re-handshake state

MatrixSSL 1.2.1

Bug fixes and optimizations

• Increased max SSL record length to 16K + 2K for Apache compatibility
• Validate outgoing record length in matrixSslEncode()
• Sanity check mac padding loop
• Validate all ASN.1 length fields in X.509 certificates

MatrixSSL 1.2

Functional changes

• Added re-handshake support

- A connected server may issue a HelloRequest message to the client
- A connected client may issue a new ClientHello message to the server
• Added support for certificate chaining
• Added RSA_WITH_NULL_SHA1 and RSA_WITH_NULL_MD5 ciphers to provide authentication and tamper detection without encryption overhead. (Because these are less secure ciphers, they must be explicitly enabled in cipherSuite.c).

• Cleaned up several mismatched types (mostly unsigned char to char compiler warnings)
• Rework of the cipher suite logic to support re-handshaking
• Rename internal APIs to avoid namespace issues with other packages

• Added matrixSslSetSessionOption()
• Added matrixSslEncodeHelloRequest()
• Added 'next' member to the sslCertInfo_t structure. This member creates a linked list to expose certificate chains to the user.

MatrixSSL 1.1.2

Bug fixes and optimizations

• Remove newline requirement for private key parsing
• Allow NULL certificate for matrixSslReadKeys()
• Cleaned up some spurious compiler warnings

MatrixSSL 1.1.1

Functional changes

• Enabled SSL_RSA_WITH_3DES_EDE_CBC_SHA by default. The footprint remains the same, since 3DES was already included with the USE_ENCRYPTED_PRIVATE_KEYS define. Note that this is the preferred cipher for many SSL clients, so by enabling this cipher, communications will default to a stronger, but slower cipher.

• Safer memory usage for RSA blinding function. Code was already safe for 1024 and 2048 bit keys, but this ensures the safety.


• Properly compare the time in the session cache to ensure the oldest unused session is replaced first. Previously the oldest session may not have been chosen, and a newer one replaced instead.


• Fixed a null-termination error in a static buffer that caused a crash on some platforms using encrypted private keys.


• Improved example code handling of return codes of sslRead(). Clarified that a 0 return code may indicate either a successful parse of a record with no application data, or an EOF. Previously both cases were treated as EOF, which fits the examples, but isn't as useful for other applications.

MatrixSSL 1.1

Enhancements

• Added session cache expiry code (defaults to 24 hours)
• Added optional support for RSA blinding (USE_RSA_BLINDING, off by default)
• Support for VxWorks
• Support for MacOS X
• Support for Microsoft Windows CE
• Support for platforms without native 64 bit integers (USE_INT64, on by default)

Changes

• Split matrixSsl.c into two additional files: sslDecode.c and sslEncode.c
• Updated matrixSslSetCertValidator() API and callback to support user supplied argument
• Added sigHash and sigHashLen parameters to sslCertInfo_t structure for public access to the certificate fingerprint
• General code formatting and cleanup
• Removed strtok() and va_args use for better portability

Fixes

• Support for (ignoring) TLS extensions in ClientHello
• Fixed bug in handling of static strings for matrixSslReadKeys()
• Fixed maximum 4 byte memory compare overrun in certificate parsing

MatrixSSL 1.0.2

This release fixes two issues; an error in parsing packed handshake records, and a corner case memory leak in the socket example code. Neither of these issues presents a security risk, but could affect interoperability and resource usage.

MatrixSSL 1.0.1

We've released a minor update to 1.0. Support has been added for validation of X.509 certificates with serial numbers using more than 32 bits, improving compatibility with more certificates. This change affects the public sslCertInfo_t structure serialNumber field type and adds a new element, serialNumberLen to the structure.

1.0 Release

We've posted our 1.0 release of MatrixSSL. Thank you to all the beta testers who sent us feedback and suggestions. We're sure the requirements will continue to be enhanced as additional products use MatrixSSL, but thanks to the open source community, this has been a strong 1.0 release.

Beta2 R2

We've released an updated Beta 2 package to fix an issue with the example certificate file included with the initial release. This certificate contained extensions that were not readable by Netscape 7 or Mozilla. We have regenerated the certificates and included them in the latest source download, with an update to asn1.c. These certificates are only for testing purposes and should not be used in an actual release.

MatrixSSL 1.0 Beta 2

We have just released a second beta version of MatrixSSL for download. Final release is just around the corner, but we wanted to get our client side SSL implementation some beta time.

Release Notes:

• RC4-MD5 and RC4-SHA are now enabled by default.
• httpClient and httpReflector must be "Set As StartUp Project" project in their respective VisualStudio solutions in order to run automatically in the debugger in Windows.
• Certificate validation currently checks only that the certificate was signed by the root CA, and that other internals are consistent. User level checks of the distinguished name will be added in final release.

Change Log:

• Added client side SSL support
• Added X.509 certificate parsing and basic validation
• Added httpClient example
• Added several new APIs for client side SSL
• Enhanced client and reflector example with support for pipelined requests
• Fixed length check in record parsing that could lead to a comparison beyond memory boundaries.
• Fixed SSL record version check that could allow invalid record versions to be sent. As only SSLv3 was supported, this did not cause a security concern.
• Added workaround for bug in Microsoft Internet Explorer, where negotiated version is sent in the encrypted premaster secret, rather than the requested version as per specification.
• Minor updates to cryptography code suggested by Tom St. Denis.

MatrixSSL 1.0 Beta

First general public release of MatrixSSL.
