This memo specifies the data structure representation that was
devised to support Simple Public Key Infrastructure (SPKI)
certificates, as detailed in RFC 2692, with the intent that it be
more widely applicable. It has been and is being used elsewhere.
There are multiple implementations in a variety of programming
languages. Uses of this representation are referred to in this
document as "S-expressions". This memo makes precise the encodings
of these SPKI S-expressions: It gives a "canonical form" for them,
describes two "transport" representations, and also describes an
"advanced" format for display to people.
INFORMATIONAL: This memo provides information for the Internet community.
It does not specify an Internet standard of any kind. Distribution of
this memo is unlimited.
