MGF1 digest and OAEP label.
[Steve Henson]
+ *) Add callbacks supporting generation and retrieval of supplemental
+ data entries.
+ [Scott Deboy <sdeboy@apache.org>, Trevor Perrin and Ben Laurie]
+
*) Add EVP support for key wrapping algorithms, to avoid problems with
existing code the flag EVP_CIPHER_CTX_WRAP_ALLOW has to be set in
the EVP_CIPHER_CTX or an error is returned. Add AES and DES3 wrap
