Public Key Cryptography Standards (PKCS)

  • Public key cryptography standards (PKCS) are a group of specifications developed with the aim of accelerating the deployment of algorithms featuring two separate keys - one private and one public.
  • PKCS were first developed by RSA Laboratories with the cooperation of security developers from around the world.
  • The first published release of PKCS was in 1991 as a result of the cooperation of early adaptors. The standards promote the use of cryptography techniques such as the RSA algorithm and the Schnorr signature.
  • PKCS are a group of non-vendor dependent standards that are aimed to foster better secure communications through the use of extensive cryptography.
  • The company published the standards to promote the use of the cryptography techniques to which they had patents, such as the RSA algorithm, the Schnorr signature algorithm and several others.
