New options added to openssl utility: + list-message-digest-algorithms and list-cipher-algorithms. + [Steve Henson] + + *) In addition to the numerical (unsigned long) thread ID, provide + for a pointer (void *) thread ID. This helps accomodate systems + that do not provide an unsigned long thread ID. OpenSSL assumes + it is in the same thread iff both the numerical and the pointer + thread ID agree; so applications are just required to define one + of them appropriately (e.g., by using a pointer to a per-thread + memory object malloc()ed by the application for the pointer-type + thread ID). Exactly analoguous to the existing functions + + void CRYPTO_set_id_callback(unsigned long (*func)(void)); + unsigned long (*CRYPTO_get_id_callback(void))(void); + unsigned long CRYPTO_thread_id(void); + + we now have additional functions + + void CRYPTO_set_idptr_callback(void *(*func)(void)); + void *(*CRYPTO_get_idptr_callback(void))(void); + void *CRYPTO_thread_idptr(void); + + also in . The default value for + CRYPTO_thread_idptr() if the application has not provided its own + callback is &errno. + [Bodo Moeller] + + *) Change the array representation of binary polynomials: the list + of degrees of non-zero coefficients is now terminated with -1. + Previously it was terminated with 0, which was also part of the + value; thus, the array representation was not applicable to + polynomials where t^0 has coefficient zero. This change makes + the array representation useful in a more general context. + [Douglas Stebila] + + *) Various modifications and fixes to SSL/TLS cipher string + handling. For ECC, the code now distinguishes between fixed ECDH + with RSA certificates on the one hand and with ECDSA certificates + on the other hand, since these are separate ciphersuites. The + unused code for Fortezza ciphersuites has been removed. + + For consistency with EDH, ephemeral ECDH is now called "EECDH" + (not "ECDHE"). For consistency with the code for DH + certificates, use of ECDH certificates is now considered ECDH + authentication, not RSA or ECDSA authentication (the latter is + merely the CA's signing algorithm and not actively used in the + protocol). + + The temporary ciphersuite alias "ECCdraft" is no longer + available, and ECC ciphersuites are no longer excluded from "ALL" + and "DEFAULT". The following aliases now exist for RFC 4492 + ciphersuites, most of these by analogy with the DH case: + + kECDHr - ECDH cert, signed with RSA + kECDHe - ECDH cert, signed with ECDSA + kECDH - ECDH cert (signed with either RSA or ECDSA) + kEECDH - ephemeral ECDH + ECDH - ECDH cert or ephemeral ECDH + + aECDH - ECDH cert + aECDSA - ECDSA cert + ECDSA - ECDSA cert + + AECDH - anonymous ECDH + EECDH - non-anonymous ephemeral ECDH (equivalent to "kEECDH:-AECDH") + + [Bodo Moeller] + + *) Add additional S/MIME capabilities for AES and GOST ciphers if supported. + Use correct micalg parameters depending on digest(s) in signed message. + [Steve Henson] + + *) Add engine support for EVP_PKEY_ASN1_METHOD. Add functions to process + an ENGINE asn1 method. Support ENGINE lookups in the ASN1 code. + [Steve Henson] + + *) Initial engine support for EVP_PKEY_METHOD. New functions to permit + an engine to register a method. Add ENGINE lookups for methods and + functional reference processing. + [Steve Henson] + + *) New functions EVP_Digest{Sign,Verify)*. These are enchance versions of + EVP_{Sign,Verify}* which allow an application to customise the signature + process. + [Steve Henson] + + *) New -resign option to smime utility. This adds one or more signers + to an existing PKCS#7 signedData structure. Also -md option to use an + alternative message digest algorithm for signing. + [Steve Henson] + + *) Tidy up PKCS#7 routines and add new functions to make it easier to + create PKCS7 structures containing multiple signers. Update smime + application to support multiple signers. + [Steve Henson] + + *) New -macalg option to pkcs12 utility to allow setting of an alternative + digest MAC. + [Steve Henson] + + *) Initial support for PKCS#5 v2.0 PRFs other than default SHA1 HMAC. + Reorganize PBE internals to lookup from a static table using NIDs, + add support for HMAC PBE OID translation. Add a EVP_CIPHER ctrl: + EVP_CTRL_PBE_PRF_NID this allows a cipher to specify an alternative + PRF which will be automatically used with PBES2. + [Steve Henson] + + *) Replace the algorithm specific calls to generate keys in "req" with the + new API. + [Steve Henson] + + *) Update PKCS#7 enveloped data routines to use new API. This is now + supported by any public key method supporting the encrypt operation. A + ctrl is added to allow the public key algorithm to examine or modify + the PKCS#7 RecipientInfo structure if it needs to: for RSA this is + a no op. + [Steve Henson] + + *) Add a ctrl to asn1 method to allow a public key algorithm to express + a default digest type to use. In most cases this will be SHA1 but some + algorithms (such as GOST) need to specify an alternative digest. The + return value indicates how strong the prefernce is 1 means optional and + 2 is mandatory (that is it is the only supported type). Modify + ASN1_item_sign() to accept a NULL digest argument to indicate it should + use the default md. Update openssl utilities to use the default digest + type for signing if it is not explicitly indicated. + [Steve Henson] + + *) Use OID cross reference table in ASN1_sign() and ASN1_verify(). New + EVP_MD flag EVP_MD_FLAG_PKEY_METHOD_SIGNATURE. This uses the relevant + signing method from the key type. This effectively removes the link + between digests and public key types. + [Steve Henson] + + *) Add an OID cross reference table and utility functions. Its purpose is to + translate between signature OIDs such as SHA1WithrsaEncryption and SHA1, + rsaEncryption. This will allow some of the algorithm specific hackery + needed to use the correct OID to be removed. + [Steve Henson] *) Remove algorithm specific dependencies when setting PKCS7_SIGNER_INFO structures for PKCS7_sign().
