Changes between 1.0.0e and 1.0.1 [xx XXX xxxx]
+ *) New -sigopt option to the ca, req and x509 utilities. 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.
