Open Source PHP Cryptography Software

Halite is a high-level cryptography interface that relies on libsodium for all of its underlying cryptography operations. Halite was created by Paragon Initiative Enterprises as a result of our continued efforts to improve the ecosystem and make cryptography in PHP safer and easier to implement. You can read the Halite Documentation online. Halite is released under Mozilla Public License 2.0. Commercial licenses are available from Paragon Initiative Enterprises if you wish to extend Halite without making your derivative works available under the terms of the MPL. If you are satisfied with the terms of MPL software for backend web applications but would like to purchase a support contract for your application that uses Halite, those are also offered by Paragon Initiative Enterprises.

An open source implementation of the FIDO2 protocol to support passwordless strong authentication using public-key cryptography. Supports registration, authentication (all platforms), and transaction authorization (for native Android apps).

[[We are in the progress of moving to github]] Metalinks is a project to facilitate data distribution over mirrors and P2P networks. It does so by defining an XML format and the tools to handle these. The metalink files contain all the information needed to download and verify files.

ActiveLock is an open-source copy protection, software licensing framework for all development enviroments supporting COM+ architecture. Core DLL available in VB2008 and VB6. Samples in C++, C#, Excel/Access VBA and keygens in PHP, ASP.NET available.

NewPKI is a PKI based on the OpenSSL low-level API, all the datas are handled through a database, which provides a much more flexible PKI than with OpenSSL, such as seeking a certificate with a search engine.

This script is capable of cracking multiple hashes from a CSV-file like e.g. dumps from sqlmap. Over 17.000 md5-hashes in a CSV-file get cracked with a 14.300.000 lines wordlist in less then 1 min. Lines wich cant get cracked with the wordlist get stored in a .leftToCrack-File to further process with another Wordlist or the bruteforce-tool. In addition to the wordlist-cracker I created also a bruteforce-tool named CSVHashBrutforcer.

Bloppy Blowfish PHP (En/De)crypter can crypt, with a private key, text messages or files, send it via e-mail and decrypt it. You can inject a crypted message into any kind of file (like JPEG image) and send it via e-mail.

ES-E is a fully downloaded encryption algorithm that you can use for your WebServer or use it for your programs (by grabbing the output off the webpage). Check the Files page for the latest build.

This tool can create one-time-password values based on HOTP (RFC 4226: HOTP: An HMAC-Based One-Time Password Algorithm), TOTP (RFC 6238: TOTP: Time-Based One-Time Password Algorithm) and OCRA (RFC 6287: OCRA: OATH Challenge-Response Algorithm) standards, and also supports client side of OAuth protocols (1.0a, 2.0).

Flash/PHP adaptation of the XTEA encryption algorithm. Allows encryption/decryption of sensitive data using 128-bit key. May be used for network data (HTTP) or offline for implementations like secure CD-ROM projects.

Strong 2 way encryption class for PHP (Uses the mcrypt PHP extension)

AUM is an extremely fast, small-state, cryptographically secure pseudo-random number generator and stream cipher. AUM exhibits uniform distribution, mixes rapidly, has no detected bias, and comes in three variants: AUM16, with an internal state array of 16+4 32-bit words; AUM32, with an internal state of 32+4 words; and AUM64 with a 64+4-word state. The former permit seeding with a key of up to 512 or 1024 bits, the latter with a 2048-bit key.

Adytum is a certificate authority suite, powered by OpenSSL, specifically designed for internal use small enterprises which need a secure and robust PHP solution without the rich feature set of software aimed at large retail CAs.
