Khoorio is a FTP client that allows you to safely encrypt your files with the AES Rijndael cipher before uploading them to a FTP server. The key used to encrypt the files is derived by a key derivation function (HMAC-SHA1) as follows: encryptionKey = HMAC-SHA1(hash_plaintext_file,user chosen master password). With this key the user allows someone to decrypt a specific file, without the need to share his master password to that person.

MOTET is a tiny, fast super-encipherment application written in C, featuring the new CSPRNG/stream ciphers MOTE and BEDBUG in each of their three variants, as well as the "gold standard" among ciphers, ISAAC. MOTET brings multiple levels of encryption, including a ciphertext-hash, a Vigenere mixing function, a choice of Caesar MOD or Caesar MIX ciphering on the primary key-stream, plus a deeply scrambled "outer shell" as a final super-encryption stage. A unique nonce IV guarantees that...

ISAAC is a cryptographically secure pseudo-random number generator (CSPRNG) and stream cipher. It was developed by Bob Jenkins from 1993-1996 and placed in the Public Domain. ISAAC is fast - especially when optimised - and portable to most architectures in nearly all programming and scripting languages. After more than 20 years of existence ISAAC has not been broken, and the little program you have here allows you to use it to encrypt and decrypt text of arbitrary length, files of any type, on a key-phrase of any complexity. ...

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...

A simple but fully-featured implementation of the simple Caesar Cipher encryption algorithm, specifically 'rot13' - Caesar with a factor of 13. Supports file and tty input/output, internationalisation, and also includes a shared library.

This small simple secure mail interface allows users to create messages, encrypt them with a password using the Enigma cipher and then send them to anyone with an email account.
