// verify the signature on a prc file. The actual
|
|
// public keys themselves are generated by the
|
|
// make-prc-key utility; the output of this utility is a
|
|
// .cxx file which should be named by the
|
|
// PRC_PUBLIC_KEYS_FILENAME variable in Config.pp.
|
|
//
|
|
// This class requires the OpenSSL library.
