PKCS #7 (PKCS7, Cryptographic Message Syntax Standard) defines standard formats for messages secured using public-key cryptography. S/MIME, a format for secure e-mail messages, is based in part on PKCS7.

As of version 1.5, PKCS7 defines six content types:

  • Data
  • Signed data
  • Enveloped data
  • Signed-and-enveloped data
  • Digested data
  • Encrypted data
