OpenSSL::Cipher(3)

NAME
OpenSSL::Cipher -- Access to OpenSSL Cipher functions

SYNOPSIS
        use OpenSSL::Cipher qw(new_encrypt new_decrypt enum_ciphers);

        my %cip = enum_ciphers();
        print "cipher \"$_\" keybytes = $cip{$_}\n" for(keys %cip);

        $ctx = new_encrypt("des-ede", "keykeyke");
        $enc = $ctx->update("hi wappla !");
        $enc .= $ctx->update ("this, too");
        $enc .= $ctx->final;

DESCRIPTION
        hmm. many things to add, but no time...

FUNCTIONS

$ctx = new_encrypt($cipname, $key)
    Creates a handle for encryption method $ciphername using key $key.

$ctx = new_decrypt($cipname, $key)
    Creates a handle for decryption method $ciphername using key $key.

$encdec = $ctx->update($string)
    Adds $string for en/decryption.

$restbytes = $ctx->final
    Finishes the encryption/decryption.

%cip = enum_ciphers();
    Returns a list that consists of "ciphername, keybytes" pairs.
