Additional + signature parameters can be passed using this option and in + particular PSS. + [Steve Henson] + + *) Add RSA PSS signing function. This will generate and set the + appropriate AlgorithmIdentifiers for PSS based on those in the + corresponding EVP_MD_CTX structure. No application support yet. + [Steve Henson] + + *) Support for companion algorithm specific ASN1 signing routines. + New function ASN1_item_sign_ctx() signs a pre-initialised + EVP_MD_CTX structure and sets AlgorithmIdentifiers based on + the appropriate parameters. + [Steve Henson] + + *) Add new algorithm specific ASN1 verification initialisation function + to EVP_PKEY_ASN1_METHOD: this is not in EVP_PKEY_METHOD since the ASN1 + handling will be the same no matter what EVP_PKEY_METHOD is used. + Add a PSS handler to support verification of PSS signatures: checked + against a number of sample certificates. + [Steve Henson] + + *) Add signature printing for PSS. Add PSS OIDs. + [Steve Henson, Martin Kaiser <lists@kaiser.cx>] + + *) Add algorithm specific signature printing. An individual ASN1 method + can now print out signatures instead of the standard hex dump. + + More complex signatures (e.g. PSS) can print out more meaningful + information. Include DSA version that prints out the signature + parameters r, s. + [Steve Henson] + *) Password based recipient info support for CMS library: implementing RFC3211.
