SPKI (5)

The IETF Simple Public Key Infrastructure Working Group has defined a format for storing, transmitting and manipulating certificates to support security in a wide range of Internet applications which will require the use of public key certificates.

For the definition of the SPKI format, please refer to [SPKI].

The format of SPKI objects is a simplified form of S-expression. An S-expression is a list enclosed in matching "(" and ")", similar to the recursive list data structure in of the LISP and Scheme programming languages.

A canonical S-expression is a unique representation of an S-expression which may contain arbitrary binary byte strings. For transport over a 7-bit channel, it may be base64 (see [RFC2045]) encoded.

The advanced S-expression format is a complexer form of an S-expression which is not necessarily unique. It is more suited for human reading than the canonical S-expression format.

Examples SPKI certificates can be found in [SPKI].
