PKCS #1: RSA Cryptography Specifications Version 2.2
Abstract
This document provides recommendations for the implementation of
public-key cryptography based on the RSA algorithm, covering
cryptographic primitives, encryption schemes, signature schemes with
appendix, and ASN.1 syntax for representing keys and for identifying
the schemes.
This document represents a republication of PKCS #1 v2.2 from RSA
Laboratories' Public-Key Cryptography Standards (PKCS) series. By
publishing this RFC, change control is transferred to the IETF.
This document also obsoletes RFC 3447.
