We are pleased to announce the availability of GnuTLS version 1.2.8. GnuTLS is a modern C library that implement the standard network security protocol Transport Layer Security (TLS), for use by network applications.
This is the last non-bugfix release in the 1.2.x series. We will open the 1.3.x branch after this release. The goal of 1.3.x will be to merge work currently done on CVS branches, for TLS Pre-Shared-Keys and TLS Inner Application. Other planned improvements in 1.3.x are system-independent resume data structures, modularization of the bignum operations, and TLS OpenPGP improvements. This release disable the RSA-MD5 algorithm when verifying untrusted intermediary X.509 CA certificates. This decision was made based on the results in Lenstra, Wang and Weger's "Colliding X.509 Certificates". This is discussed in more detail, including instructions on how to re-enable the algorithm for application's that need backwards compatibility, in: http://josefsson.org/gnutls/manual/html_node/Digital-signatures.html Noteworthy changes since version 1.2.8: - Documentation was updated and improved. - RSA-MD2 is now supported for verifying digital signatures. - Due to cryptographic advances, verifying untrusted X.509 certificates signed with RSA-MD2 or RSA-MD5 will now fail with a GNUTLS_CERT_INSECURE_ALGORITHM verification output. For applications that must remain interoperable, you can use the GNUTLS_VERIFY_ALLOW_SIGN_RSA_MD2 or GNUTLS_VERIFY_ALLOW_SIGN_RSA_MD5 flags when verifying certificates. Naturally, this is not recommended default behaviour for applications. To enable the broken algorithms, call gnutls_certificate_set_verify_flags with the proper flag, to change the verification mode used by gnutls_certificate_verify_peers2. - Make it possible to send empty data through gnutls_record_send, to align with the send(2) API. - Some changes in the certificate receiving part of handshake to prevent some possible errors with non-blocking servers. - Added numeric version symbols to permit simple CPP-based feature tests, suggested by Daniel Stenberg <[EMAIL PROTECTED]>. - The (experimental) low-level crypto alternative to libgcrypt used earlier (Nettle) has been replaced with crypto code from gnulib. This leads to easier re-use of these components in other projects, leading to more review and simpler maintenance. The new configure parameter --with-builtin-crypto replace the old --with-nettle, and must be used if you wish to enable this functionality. See README under "Experimental" for more information. Internally, GnuTLS has been updated to use the new "Generic Crypto" API in gl/gc.h. The API is similar to the old crypto/gc.h, because the gnulib code were based on GnuTLS's gc.h. - Fix compiler warning in the "anonself" self test. - API and ABI modifications: gnutls_x509_crt_list_verify: Added 'const' to prototype in <gnutls/x509.h>. This doesn't reflect a change in behaviour, so we don't break backwards compatibility. GNUTLS_MAC_MD2: New gnutls_mac_algorithm_t value. GNUTLS_DIG_MD2: New gnutls_digest_algorithm_t value. GNUTLS_VERIFY_ALLOW_SIGN_RSA_MD2, GNUTLS_VERIFY_ALLOW_SIGN_RSA_MD5: New gnutls_certificate_verify_flags values. Use when calling gnutls_x509_crt_list_verify, gnutls_x509_crt_verify, or gnutls_certificate_set_verify_flags. GNUTLS_CERT_INSECURE_ALGORITHM: New gnutls_certificate_status_t value, used when broken signature algorithms is used (currently RSA-MD2/MD5). LIBGNUTLS_VERSION_MAJOR, LIBGNUTLS_VERSION_MINOR, LIBGNUTLS_VERSION_PATCH, LIBGNUTLS_VERSION_NUMBER: New CPP symbols, indicating the GnuTLS version number, can be used for feature existence tests. Improving GnuTLS is costly, but you can help! We are looking for organizations that find GnuTLS useful and wish to contribute back. You can contribute by reporting bugs, improve the software, or donate money or equipment. Commercial support contracts for GnuTLS are available, and they help finance continued maintenance. Simon Josefsson Datakonsult, a Stockholm based privately held company, is currently funding GnuTLS maintenance. We are always looking for interesting development projects.
