PKCS V1.5 Signature Scheme Functions

This algorithm is considered weak due to known attacks on it. The functionality remains in the library, but the implementation will no longer be optimized and no security patches will be applied. A more secure alternative is available: RSA-OAEP. For more information, see PKCS #1 v2.1: RSA Cryptography Standard (

This subsection describes functions implementing the RSASSA-PKCS1-v1_5 signature scheme with appendix [PKCS 1.2.1].
