    Conscrypt

    Conscrypt

    Conscrypt is a Java Security Provider

    ...It is implemented as a drop-in SecurityProvider, so applications and frameworks can opt in without changing high-level HTTPS or socket code. The provider focuses on contemporary protocol hygiene—up-to-date cipher suite selection, ALPN, session resumption, and hardened defaults—so Java servers and clients negotiate secure connections by construction. Because it builds on BoringSSL’s audited primitives and constant-time implementations, it reduces the risk of subtle side-channel issues while improving handshake and bulk crypto throughput. Conscrypt also exposes platform accelerations (like AES-GCM and ChaCha20-Poly1305) and supports features important to HTTP/2 and HTTP/3 stacks. ...

    transcrypt git

    transcrypt git

    transparently encrypt files within a git repository

    A script to configure transparent encryption of sensitive files stored in a Git repository. Files that you choose will be automatically encrypted when you commit them, and automatically decrypted when you check them out. The process will degrade gracefully, so even people without your encryption password can safely commit changes to the repository's non-encrypted files. transcrypt protects your data when it's pushed to remotes that you may not directly control (e.g., GitHub, Dropbox clones,...

    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).

    RotorCrypt X

    Free offline encryption – Enigma + AES-256-GCM – no cloud

    RotorCrypt X is a free offline hybrid encryption software for Windows 10/11 that protects private messages with six independent cryptographic layers — making interception practically impossible even if all stored files are compromised. Six cryptographic layers: Enigma rotor cipher with up to 50 rotors and 241-digit key combinations. AES-256-GCM military-grade authenticated encryption. HKDF-SHA3-256 key derivation with Perfect Forward Secrecy. Argon2id password hardening — 256 MB RAM per attempt, brute-force practically impossible even on GPU clusters. Split Key via ECDH Curve25519 — neither party alone can compute the shared key. ...

    bitcrypt

    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 information to another party, you may encrypt it using BitCrypt and publish it as a part of a website. ...
