PEM(8)                                                     PEM(8)

     NAME
          pemdecode, pemencode - encode files in Privacy Enhanced Mail
          (PEM) format

     SYNOPSIS
          auth/pemdecode section [ file ]

          auth/pemencode section [ file ]

     DESCRIPTION
          PEM is a textual encoding for binary data originally used by
          the Privacy Enhanced Mail program but now commonly used for
          other applications, notably TLS.  PEM encodes data in base
          64 (see encode(2)) between lines of the form:

               -----BEGIN SECTION-----
               -----END SECTION-----

          where SECTION may be any string describing the encoded data.
          The most common use of PEM format on Plan 9 is for encoding
          X.509 certificates; see rsa(8).

          Pemdecode extracts the named section and writes the decoded
          data to standard output.

          Pemencode encodes its standard input, labels it as a
          section, and writes it to standard output.

     EXAMPLES
          Encode and decode a simple greeting:

               % echo hello world |
                    auth/pemencode GREETING
               -----BEGIN GREETING-----
               aGVsbG8gd29ybGQK
               -----END GREETING-----
               % echo hello world |
                    auth/pemencode GREETING |
                    auth/pemdecode GREETING
               hello world
               %
