S-expression latter intended to safely transport a canonically encoded S-expression in a system which might change spacing (e.g. an email system which has 80-character-wide lines and wraps anything longer than that). This format has not been widely adapted for use outside of SPKI (some of the users being GnuPG, libgcrypt, Nettle, and GNU lsh). Rivest's S-expressions web page provides C source code for a parser and generator (available under the MIT license), which could be adapted and embedded into other programs. In addition, there are no restrictions on independently implementing the format. Free software implementations are available: S-expression In computing, s-expressions,
