PKCS #5: Password-Based Cryptography Specification Version 2.1
RFC 8018, “PKCS #5: Password-Based Cryptography Specification Version 2.1”, is an Informational document published in January 2017 by K. Moriarty, B. Kaliski, A. Rusch. It obsoletes RFC 2898. It has since been updated by RFC 9579, RFC 9879. The canonical text is published by the RFC Editor.
Abstract
This document provides recommendations for the implementation of password-based cryptography, covering key derivation functions, encryption schemes, message authentication schemes, and ASN.1 syntax identifying the techniques.
This document represents a republication of PKCS #5 v2.1 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 2898.
