Legacy bits of security constraint. By default, legacy algorithms are all acceptable but can only be used for decryption and verification tasks. Algorithms with the required bits of security can be used for anything. If a minimum level of security is given for legacy algorithms, then anything below that will be treated as an error unless it appears in the exception list.
