I'd like to upload Crypt::NULL (README appended), a module implementing NULL encryption as described in RFC 2410, to the CPAN. Please suggest an alternative name is Crypt::NULL is unsuitable. modid: Crypt::NULL DSLI: RdpO description: NULL Encryption Algorithm userid: AMS (Abhijit Menon-Sen) chapterid: 14 (Security_and_Encryption) - ams NAME Crypt::NULL - NULL Encryption Algorithm SYNOPSIS use Crypt::NULL; $null = Crypt::NULL->new($key); $ciphertext = $null->encrypt($plaintext); $plaintext = $null->decrypt($ciphertext); DESCRIPTION The NULL Encryption Algorithm is a symmetric block cipher described in RFC 2410 by Rob Glenn and Stephen Kent. This module implements NULL encryption. It supports the Crypt::CBC interface, with the following functions. Functions blocksize Returns the size (in bytes) of the block (16, in this case). keysize Returns the size (in bytes) of the key (16, in this case). new($key, $rounds) This creates a new Crypt::NULL object with the specified key. encrypt($data) Encrypts blocksize() bytes of $data and returns the corresponding ciphertext. decrypt($data) Decrypts blocksize() bytes of $data and returns the corresponding plaintext.
