Crypt-OpenSSL-CA - Model of an X509v3 Certification Authority This package performs the cryptographic operations necessary to issue X509 certificates and certificate revocation lists (CRLs). It is implemented as a Perl wrapper around the popular OpenSSL library. All certificate and CRL extensions supported by OpenSSL are available, and then some.

This module provides a standard (non-OO) interface to the OpenSSL EC (Elliptic Curve) library. Some OO Calls are supported. Most of the functions described in openssl/ec.h are supported.

This perl extension is an implementation of the IDEA block cipher algorithm. The module implements the Crypt::BlockCipher interface, which has the following methods blocksize =item keysize =item encrypt =item decrypt

This package is used to encrypt and decrypt passwords generated by IMail. See: http://www.ipswitch.com/products/imail_server/

This module provides an interface to the ECDSA (Elliptic Curve Digital Signature Algorithm) functions in OpenSSL.

Khazad is a 128-bit key, 64-bit block cipher. Designed by Vincent Rijmen and Paulo S. L. M. Barreto, Khazad is a NESSIE finalist for legacy-level block ciphers. Khazad has many similarities with Rijndael, and has an extremely high rate of diffusion.

Crypt::License decodes an encrypted file and attempts to decrypt it by first, looking for a hash pointer in the caller program called $ptr2_License. The hash contains the path to the License file and an optional 'private' key list of modules which will decrypt only with the 'private' key. OR, a hash key of 'next' with no particular value that indicates to look to the next caller on the stack for the License pointer. If the pointer is not present or the License file is not found successfully, then no further action is taken. If the License file is successfully opened, and the contents validated then the attached encrypted module is loaded and the seconds remaining until License expiration are returned or now() in the case of no expiration. Undef is returned for an expired license (module fails to load).

Loki97 is 128-bit block cipher that accepts a variable-length key. It was designed by Lawrie Brown, Josef Pieprzyk, and Jennifer Seberry. The default key length in this implementation is 128 bits. Loki97 was one of the 15 candidates for the AES.

Perl extension to OpenSSL's PKCS10 API.

Crypt::OpenSSL::RSA provides the ability to RSA encrypt strings which are somewhat shorter than the block size of a key. It also allows for decryption, signatures and signature verification.
