NAME
SPKI - Simple Public Key Infrastructure formats
DESCRIPTION
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.
Canonical S-expression
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.
Advanced S-expression
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.
EXAMPLE
Examples SPKI certificates can be found in [SPKI].
