CenoCipher - Easy-To-Use, End-To-End Encrypted Communications Tool
CenoCipher is a free, open-source, easy-to-use tool for exchanging secure encrypted communications over the internet. It uses strong cryptography to convert messages and files into encrypted cipher-data, which can then be sent to the recipient via regular email or any other channel available, such as instant messaging or shared cloud storage.
Features at a glance
- Simple for anyone to use. Just type a message, click Encrypt, and go
- Handles messages and file attachments together easily
- End-to-end encryption, performed entirely on the user's machine
- No dependence on any specific intermediary channel. Works with any communication method available
- Uses three strong cryptographic algorithms in combination to triple-protect data
- Optional steganography feature for embedding encrypted data within a Jpeg image
- No installation needed - fully portable application can be run from anywhere
- Unencrypted data is never written to disk - unless requested by the user
- Multiple input/output modes for convenient operation
Technical details
- Open source, written in C++
- AES/Rijndael, Twofish and Serpent ciphers (256-bit keysize variants), cascaded together in CTR mode for triple-encryption of messages and files
- HMAC-SHA-256 for construction of message authentication code
- PBKDF2-HMAC-SHA256 for derivation of separate AES, Twofish and Serpent keys from user-chosen passphrase
- Cryptographically safe pseudo-random number generator ISAAC for production of Initialization Vectors (AES/Twofish/Serpent) and Salts (PBKDF2)
