Changes between 0.9.8a and 0.9.9 [xx XXX xxxx]
+ *) Transfer public key printing routines to EVP_PKEY_ASN1_METHOD. New
+ functions EVP_PKEY_print_public(), EVP_PKEY_print_private(),
+ EVP_PKEY_print_param() to print public key data from an EVP_PKEY
+ structure.
+ [Steve Henson]
+
*) Initial support for pluggable public key ASN1.
De-spaghettify the public key ASN1 handling. Move public and private
key ASN1 handling to a new EVP_PKEY_ASN1_METHOD structure. Relocate
