...For purposes of speed, OpenSSL, GMP, libsodium or mcrypt are used, if they're available, but they are not required. phpseclib is designed to be fully interoperable with standardized cryptography libraries and protocols. MIT-licensed pure-PHP implementations of SSH-2, SFTP, X.509, an arbitrary-precision integer arithmetic library, Ed25519 / Ed449 / Curve25519 / Curve449, ECDSA / ECDH (with support for 66 curves), RSA (PKCS#1 v2.2 compliant), DSA / DH, DES / 3DES / RC4 / Rijndael / AES / Blowfish / Twofish / Salsa20 / ChaCha20, GCM / Poly1305. ...

This is a simple web tool which allows users of a website to "securely" submit messages and files. They are sent over HTTPS to the server and there encrypted and forwarded to the administrator.

This software shall enable users to send / receive denyable messages: Nobody can prove a message is from / for a specific user. Messages can be made private (by using password) or are public. All messages have an expiration time/date / event

[[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.

AleHu is an open source encrypted message transfer system that encompasses both server (PHP) and client software (Java). Give it a shot: You can try out AleHu by simply running the client using the preconfigured AleHu test server! For further details and instructions on how to quickly install and run AleHu, have a look at the documentation in the Wiki section.

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.

SES brings back the uncrackable onetime pad, with a digital twist. It is well known that a random key of message-length is the only provably unbreakable cipher. SES uses cryptographic strength pseudo-random keys of message-length for its many encipherments, in addition to offering true one-time pad capability for the intrepid. SES is built on ISAAC, Bob Jenkins' unbroken CSPRNG, a fast and simple stream cipher placed in the Public Domain in 1996. SES now gives you the ability to...

Remix of the permutation ciphers' design for better security. I tried to solve the issue of frequency analysis and brute force attacks by joining padding and the alphabet matching (I called it the alpha-padding) View a demo here: http://igenda.netau.net/codijuana/alphapadding_permutation/

Free Tiger aims to provide a fast C implementation of the tiger and TTH hash algorithms in order to provide a performing hasher. It also aims to provide pure implementations of tiger and when possible TTH in other languages for reference.
