NAME crypt - encrypt and decrypt standard input SYNOPSIS crypt key DESCRIPTION Crypt encrypts characters on the standard input by using "key". The file can eventually be decrypted by running it back through crypt with the same key. Multiple encryption (encrypting a file with first one key and then another) is allowable. The size of the encryption key is limited by the MAXKEY definition in the source code. FILES None SEE ALSO DIAGNOSTICS None AUTHORS From Kernighan & Plauger's 'Software Tools'. BUGS/DEFICIENCIES On some systems, encryption results in control characters which may cause erratic behavior. For these systems, an optional version of the encryption routine is provided which avoids encrypting control characters. When using this optional version, multiple decriptions must be done in the exact reverse order in which encryption was done.
