commit c9fe362303fc54ff19bde7511475f28663f7d554
Author: Matt Caswell <matt at openssl.org>

    Correct value for BN_security_bits()
    
    The function BN_security_bits() uses the values from SP800-57 to assign
    security bit values for different FF key sizes. However the value for 192
    security bits is wrong. SP800-57 has it as 7680 but the code had it as
    7690.
