Changes between 0.9.8a and 0.9.9 [xx XXX xxxx]
+ *) 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
