transcrypt git
transparently encrypt files within a git repository
....), while still allowing you to work normally on your local working copy. You can conveniently store things like passwords and private keys within your repository and not have to share them with your entire team or complicate your workflow. transcrypt is in the same vein as existing projects like git-crypt and git-encrypt, which follow Git's documentation regarding the use of clean/smudge filters for encryption. -

Grain128AEAD
A lightweight AEAD stream cipher submitted to the CAESAR competition
Grain is a stream cipher submitted to eSTREAM in 2004 by Martin Hell, Thomas Johansson and Willi Meier. It has been selected for the final eSTREAM portfolio for Profile 2 by the eSTREAM project. Grain is designed primarily for restricted hardware environments. It accepts an 80-bit key and a 64-bit IV. The specifications do not recommended a maximum length of output per (key, iv) pair. A number of potential weaknesses in the cipher have been identified and corrected in Grain 128a which is now... -

BIP39-XOR
Encrypt or decrypt 12, 15, 18, 21 or 24 BIP39 codewords array ("seed")
Encrypt or decrypt 12, 15, 18, 21 or 24 BIP39 codewords array (so-called "seed phrase") using exclusive OR (XOR)/Vernam cipher (a.k.a. One Time Pad). If not input by a user, an encryption key is automatically generated at random. Encryption with such a key preserves integrity of BIP-39 checksums of all keys (that's distinct while also compatible with SeedXOR implementation). -

bitcrypt
BitCrypt is a free ultra-strong encryption that hides text in bitmaps.
BitCrypt is an elegant encryption that allows for the storage and transmission of information in an undetectable manner. The program processes a user-supplied text encrypting it with the Rijndael cipher and storing it in a user-selected bitmap image. This later step is called steganography, which means "to hide invisibly". If you intend to store sensitive information invisibly, you may encrypt it with BitCrypt and keep it in a picture image. Alternatively, if you intend to pass... -

AES_plus_Serpent_in_CBC_mode
Open-source code that enables you to use AES + Serpent in CBC mode
The AES_plus_Serpent_in_CBC_mode_for_microcontrollers repository contains code that enables you to encrypt your data using a combination of AES and Serpent encryption algorithms in CBC mode. In addition to that, the code in this repository enables you to verify the data integrity, thanks to the HMAC-SHA256. Attention! I didn't develop the libraries utilized by these sketches. I took them from the following repositories: https://github.com/zhouyangchao/AES https://github.com/peterferrie... -

AES_plus_Blowfish_in_CBC_mode
Open-source code that enables you to use AES + Blowfish in CBC mode
The AES_plus_Blowfish_in_CBC_mode repository contains two sketches that enable you to encrypt your data using a combination of AES and Blowfish encryption algorithms in CBC mode. The only difference between them, from the functional point of view, is that one verifies the integrity of the decrypted data (plaintext) while the other doesn't. Copyright/Ownership/Licenses Attention! I didn't develop the libraries utilized by these sketches. I took them from the following repositories: https... -

Ciphey
Decrypt encryptions without knowing the key or cipher
... to quickly check the ciphertext before working on it yourself, Ciphey is for you. The technical part. Ciphey uses a custom-built artificial intelligence module (AuSearch) with a Cipher Detection Interface to approximate what something is encrypted with. And then a custom-built, customizable natural language processing Language Checker Interface, which can detect when the given text becomes plaintext. -

approach to encryption and decryption involves two strings. The first is an encryption / decryption string which we will allow to be up to 128 lower case alphabetical characters in length. The second string is a line of text from a file that is to be encrypted or decrypted. the basic strategy for encrypting data is based on mapping alphabetical characters to specific values, then doing some simple mathematical operations to create a new value.

d-crypt
Tweakable 256-bit symmetrical block cipher.
D-crypt is an symmetrical block cipher operating on 256bit blocks with an key of the same length. The cipher takes 3 inputs: the data to encrypt, the symmetric key and a tweak consisting in a array of 16 integers representing each one of eleven possible keyaddition algorithms. Features a similar structure as AES (uses simpler versions of ShiftRows, MixColumns) and uses AES SBOX. It is an SP network. The Key Schedule is a different from AES's, however the Expansion is partially inspired in AES... -

The MOTET Cipher & SE Scrambler
A tiny, fast encryption tool in C
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 each... -

SATURN cipher
RNG for use in a stream cipher
SATURN is now a fully-functional stream cipher. It is in active development. The underlying algorithm is SATURNrng, a cryptographically-secure random number generator. SATURNrng is seeded with a 480-bit key and a 480-bit nonce which then produces a random stream used to encrypt a plaintext. -

Khoorio
FTP client to encrypt/decrypt and upload/download files
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. As it consists of a personalized key, the receiving... -

SES Super-Encypherment Scrambler
SES brings back the uncrackable onetime pad, with a digital twist.
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... -
