Some mechanisms can be used for both encryption/decryption and sign/verify such as RSA related ones. If the particular mechanism supports sign/verify/decryption but not encryption, it'd be disabled as a result. Fine tune the legacy mechanism check with the service type, i.e. supports encryption for Cipher,  sign for Signature, so the mechanism is disabled based on the service type.

LGTM
