PKCS #1: RSA Encryption Version 1
Alternative Format: Original Text Document
RFC 2313 PKCS #1: RSA Encryption March 1998 content-encryption key are represented together according to the syntax in PKCS #7 to yield a digital envelope. This application is also compatible with PEM methods. The document also describes a syntax for RSA public keys and private keys. The public-key syntax would be used in certificates; the private-key syntax would be used typically in PKCS #8 private-key information. The public-key syntax is identical to that in both X.509 and Privacy-Enhanced Mail. Thus X.509/PEM RSA keys can be used in this document. The document also defines three signature algorithms for use in signing X.509/PEM certificates and certificate-revocation lists, PKCS #6 extended certificates, and other objects employing digital signatures such as X.401 message tokens. Details on message-digest and content-encryption algorithms are outside the scope of this document, as are details on sources of the pseudorandom bits required by certain methods in this document. 2.
