Changes between 0.9.7c and 0.9.8 [xx XXX xxxx]
+ *) New function X509_POLICY_NODE_print() which prints out policy nodes.
+ [Steve Henson]
+
+ *) Add new EVP function EVP_CIPHER_CTX_rand_key and associated functionality.
+ This will generate a random key of the appropriate length based on the
+ cipher context. The EVP_CIPHER can provide its own random key generation
+ routine to support keys of a specific form. This is used in the des and
+ 3des routines to generate a key of the correct parity. Update S/MIME
+ code to use new functions and hence generate correct parity DES keys.
+ Add EVP_CHECK_DES_KEY #define to return an error if the key is not
+ valid (weak or incorrect parity).
+ [Steve Henson]
+
*) Add a local set of CRLs that can be used by X509_verify_cert() as well
as looking them up. This is useful when the verified structure may contain
CRLs, for example PKCS#7 signedData. Modify PKCS7_verify() to use any CRLs
