VeraCrypt
Open source disk encryption with strong security for the Paranoid
VeraCrypt is a free disk encryption software brought to you by IDRIX (https://www.idrix.fr) and based on TrueCrypt 7.1a. It adds enhanced security to the algorithms used for system and partitions encryption making it immune to new developments in brute-force attacks. It also solves many vulnerabilities and security issues found in TrueCrypt. This enhanced security adds some delay ONLY to the opening of encrypted partitions without any performance impact to the application use phase. This is acceptable to the legitimate owner but it makes it much harder for an attacker to gain access to the encrypted data. All released files are PGP signed with key ID=0x680D16DE, available on key servers and downloadable at https://www.idrix.fr/VeraCrypt/VeraCrypt_PGP_public_key.asc VeraCrypt can mount TrueCrypt volumes. It also can convert them to VeraCrypt format. Documentation: https://www.veracrypt.fr/en/Documentation.html FAQ : https://www.veracrypt.fr/en/FAQ.html -

Ciphey
Decrypt encryptions without knowing the key or cipher
Fully automated decryption/decoding/cracking tool using natural language processing & artificial intelligence, along with some common sense. You don't know, you just know it's possibly encrypted. Ciphey will figure it out for you. Ciphey can solve most things in 3 seconds or less. Ciphey aims to be a tool to automate a lot of decryptions & decodings such as multiple base encodings, classical ciphers, hashes or more advanced cryptography. If you don't know much about cryptography, or you want 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. -

CrococryptFile
An encryption tool for creating file archives
CrococryptFile is a file encryption tool which creates encrypted archives of files and folders. The encryption features of CrococryptFile can be compared to a ZIP utility that uses ZIP's AES encryption. However, there are significant differences. CrococryptFile... - encrypts all file and folder information including filenames, time/date and filesize information, - disguises any information of the archive's content, because all data and meta-data is simply integrated into a giant file dump. =Crypto Suites= For a full list of and details about supported crypto suites, please visit the CrococryptFile Homepage. Examples: - Password-based encryption (following PBKDF2) with AES-256, Twofish, Serpent, ... - Public key encryption using GPG/OpenPGP, Windows Keystore/CAPI with RSA/X.509 certificates - Cloaked (headerless) Password-based Encryption (AES-Twofish-256 cascaded) - ... -

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). -

Portable Text Encryption
Single Linux or Windows binary for secure text encryption
Self contained and completely portable binary encrypts text for secure email, messaging, irc use, etc., ideal for USB flash drives. AES-128/192/256 (ecb/cbc), Blowfish (ecb/cbc), DES / TripleDES (ecb/cbc/ofb/cfb), or RC4. Linux and Windows binaries. I don't make cute interfaces, it just works. https://codeberg.org/BloodFeastMan/pte I would also recommend FTC, encrypts both files and text using the same interface as PTE, and a separate encryption and hashing engine I wrote in Crystal, and is much faster than PTE: https://sourceforge.net/projects/ft-crypt/ -

JCryptor
JCryptor is an encrypting tool based on the Caesar-cipher.
JCryptor uses the Caesar-cipher to encrypt keystrokes on-the-fly. It can also be used to decrypt an encrypted text easily. Caesar-cipher is a simple encryption algorithm, developed by Julius Caesar, to encrypt his correspondence with Cicero in the ancient world. Therefore it uses a simple character substitution method to replace a given character by another. A keyshift of thirteen is called ROT13. ROT13 can be decrypted by encrypting it again with ROT13. Even today this simple method is used by authorities to protect documents from unintentional reading. --UPDATE-- [25.01.14] Release 1.0 (final) -- Bugfixes [05.05.12] Release 0.2 -- implements polyalphabeticel substitution -

Stegcore
A cross-platform crypto-steganography toolkit
Stegcore combines cryptography and steganography to hide encrypted data inside ordinary files. It encrypts your payload before embedding it, so the hidden content is unreadable even if someone extracts it, and invisible to anyone who doesn't know it's there. Unlike basic steganography tools that hide data without encrypting it, Stegcore ensures the payload is cryptographically protected at rest. Unlike pure encryption tools, the payload isn't even visible. Designed for journalists, security researchers, red teamers, digital forensics professionals, and CTF participants. -

PureBasic Shamir Secret Sharing
Open-source PureBasic implementation of the Shamir Secret Sharing
PureBasic Shamir Secret Sharing is an open-source, self-contained and educational implementation of the Shamir Secret Sharing Scheme, written entirely in PureBasic. Shamir Secret Sharing is a cryptographic method that splits a secret into multiple parts (shares), such that any combination of at least T shares can reconstruct the original secret, while any number of shares fewer than T reveals no usable information. This implementation operates over the finite field GF(257), allowing correct handling of all byte values (0–255) without loss, making it compatible with any type of string or binary-compatible data. Main Features Complete implementation of Shamir Secret Sharing Arithmetic over GF(257) Compatible with all character strings Robust Lagrange interpolation Safe modular inverse computation Shares encoded in hexadecimal (3 characters per byte) Clear, well-commented source code ⚠️ Disclaimer This project is intended for educational and demonstration -
