Crypt::Juniper - Encrypt/decrypt Juniper $9$ secrets

This module is a Perl-only implementation of the ECB mode. In combination with a block cipher such as DES, IDEA or Blowfish, you can encrypt and decrypt messages of arbitrarily long length. Though for security reasons other modes than ECB such as CBC should be preferred. See textbooks on cryptography if you want to know why. The functionality of the module can be accessed via OO methods or via standard function calls. Remember that some crypting module like for example Blowfish has to be installed. The syntax follows that of Crypt::CBC meaning you can access Crypt::ECB exactly like Crypt::CBC, though Crypt::ECB is more flexible. For example you can change the key or the cipher without having to create a new crypt object.

This module is a complete working Perl implementation of the Enigma Machine used during World War II. The cipher calculations are based on actual Enigma values and the resulting ciphered values are as would be expected from an Enigma Machine. The implementation allows for all of the Rotors and Reflectors available to the real world Enigma to be used. A Steckerboard has also been implemented, allowing letter substitutions to be made.

Crypt::MySQL emulates MySQL PASSWORD() SQL function, without libmysqlclient. You can compare encrypted passwords, without real MySQL environment.

This is Crypt::NULL. Perl module for NULL Encryption Algorithm. 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.

This module is a Perl-only implementation of the OFB mode. Where OFB stands for Output Feedback Block.

Crypt::OpenPGP is a pure-Perl implementation of the OpenPGP standard[1]. In addition to support for the standard itself, Crypt::OpenPGP claims compatibility with many other PGP implementations, both those that support the standard and those that preceded it. Crypt::OpenPGP provides signing/verification, encryption/decryption, keyring management, and key-pair generation; in short it should provide you with everything you need to PGP-enable yourself. Alternatively it can be used as part of a larger system; for example, perhaps you have a web-form-to-email generator written in Perl, and you'd like to encrypt outgoing messages, because they contain sensitive information. Crypt::OpenPGP can be plugged into such a scenario, given your public key, and told to encrypt all messages; they will then be readable only by you. This module currently supports RSA and DSA for digital signatures, and RSA and ElGamal for encryption/decryption. It supports the symmetric ciphers 3DES, Blowfish, IDEA, Twofish, and Rijndael (AES). Rijndael is supported for key sizes of 128, 192, and 256 bits. Crypt::OpenPGP supports the digest algorithms MD5, SHA-1, and RIPE-MD/160. And it supports ZIP and Zlib compression.

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

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).
