Technical Summary TLS specification versions 1.0 (RFC 2246) and 1.1 (RFC 4346) included cipher suites based on DES (Data Encryption Standard) and IDEA (International Data Encryption Algorithm) algorithms. DES (when used in single-DES mode) and IDEA are no longer recommended for general use in TLS, and have been removed from TLS 1.2 main specification (RFC 5246). This document specifies these cipher suites for completeness, and discusses reasons why their use is no longer recommended. Working Group Summary This document review was non-controversial. The longest discussion was on the use of SHOULD and MUST in an informational document. Document Quality This document deprecates ciphers, removed from TLS 1.2, that are no longer considered appropriate for general use. There is general agreement in the security community that this is the right thing to do. Personnel Joe Salowey is the Document Shepherd, and Tim Polk is the Responsible Area Director.
