KEYRING-CERTTOSTR(2) KEYRING-CERTTOSTR(2)
NAME
keyring: certtostr, pktostr, sktostr, strtocert, strtopk,
strtosk - encryption key conversion functions
SYNOPSIS
include "keyring.m"
keyring:= load Keyring Keyring->PATH;
strtocert: fn(s: string) : ref Certificate;
certtostr: fn(c: ref Certificate): string;
strtopk: fn(s: string) : ref PK;
pktostr: fn(pk: ref PK) : string;
strtosk: fn(s: string) : ref SK;
sktostr: fn(sk: ref SK) : string;
DESCRIPTION
Certificates, public keys, and private keys are passed over
networks and between applications using a Unicode
representation. This collection of functions provide a means
to convert adts supplied by the system to and from their
portable textual representation. These routines are
typically used as part of an I/O package for implementing
security.
Strtocert takes a string argument containing a user name, a
hash algorithm, a certifying authority and an expiration
time. Fields are separated by a newline. The return value is
a Certificate. If the string is of improper format, the
result is nil.
Certtostr performs the inverse operation: takes the
Certificate c and produces a text string suitable for commu-
nication over a network.
Strtopk and strtosk take as their arguments a string s rep-
resenting the public and private keys respectively. S must
contain an algorithm name, a user name and the key. Fields
are separated by a newline. Strtopk returns a reference to
the resulting PK; strtosk returns a reference to the result-
ing SK. If the format of s is invalid, the result is nil.
Pktostr and sktostr perform the inverse operations: they
take a public key (secret key) and produce a printable rep-
resentation as a string.
