A family of standards for public key cryptography that includes RSA encryption, Diffie-Hellman key agreement, password-based encryption, extended-syntax, cryptographic message syntax, private key information syntax, and certificate request syntax, as well as selected attributes. Developed, owned, and maintained by RSA Data Security, Inc. See also: certificate; public key cryptography
A group of PKI standards developed and maintained by RSA Security, covering certificate enrollment and renewal, and CRL distribution. A number of the PKCS have become standards defined by the IETF. Four of the most commonly used standards that a solution should support are: PKCS #7 - Cryptographic Message Syntax Standard PKCS #10 - Certificate Request Syntax Standard PKCS #11 - Cryptographic Token Interface Standard PKCS #12 - Personal Information Exchange Syntax Standard
