2514fa79ac Add functions returning security bits. 
Add functions to return the "bits of security" for various public key
algorithms. Based on SP800-57.

41b920ef01 Return correct enveloped data type in ASN1 methods. 
For RSA and DSA keys return an appropriate RecipientInfo type. By setting
CMS_RECIPINFO_NONE for DSA keys an appropriate error is returned if
an attempt is made to use DSA with enveloped data.

8d6a75dc3a Avoid need to change function code. 
Keep original function names for nonce versions so we don't have to change
error function codes.

190c615d43 Make `safe' (EC)DSA nonces the default. 
This change updates 8a99cb29 to make the generation of (EC)DSA nonces
using the message digest the default. It also reverts the changes to
(EC)DSA_METHOD structure.

In addition to making it the default, removing the flag from EC_KEY
means that FIPS modules will no longer have an ABI mismatch.

8a99cb29d1 Add secure DSA nonce flag. 
This change adds the option to calculate (EC)DSA nonces by hashing the
message and private key along with entropy to avoid leaking the private
key if the PRNG fails.

Dr. Stephen Henson
7f64c26588 Since FIPS 186-3 specifies we use the leftmost bits of the digest 
we shouldn't reject digest lengths larger than SHA256: the FIPS
algorithm tests include SHA384 and SHA512 tests.

245a7eee17 recalculate DSA signature if r or s is zero (FIPS 186-3 requirement) 2011-01-25 16:01:29 +00:00
Dr. Stephen Henson
198ce9a611 Add additional parameter to dsa_builtin_paramgen to output the generated 
seed to: this doesn't introduce any binary compatibility issues as the
function is only used internally.

The seed output is needed for FIPS 140-2 algorithm testing: the functionality
used to be in DSA_generate_parameters_ex() but was removed in OpenSSL 1.0.0
