Vigenère
A powerful tool for cracking the Vigenère cipher
Vigenère is a program for encrypting and decrypting text using the Vigenère cipher. Built-in cryptanalysis tools make it possible to crack the cipher without needing the key — or even knowing its length. -

kcptun
A stable and secure tunnel based on KCP with N:M multiplexing and FEC
kcptun is a stable and secure tunnel based on KCP with N:M multiplexing and FEC. Available for ARM, MIPS, 386 and AMD64. kcptun is shipped with builtin packet encryption powered by various block encryption algorithms and works in Cipher Feedback Mode, for each packet to be sent, the encryption process will start from encrypting a nonce from the system entropy, so encryption to same plaintexts never leads to a same ciphertexts thereafter. kcptun made use of ReedSolomon-Codes to recover lost packets, which requires massive amount of computation, a low-end ARM device cannot satisfy kcptun well. ... -

Cryptomator
Multi-platform transparent client-side encryption for your cloud files
Cryptomator is a free and open source project that offers multi-platform, transparent client side encryption of your files in the cloud. It works with just about any cloud storage service; is totally transparent so you can work with your files how you normally would; and secure with a 256-bit key length AES encryption. It’s also simple and easy to use with no need for different accounts, key management, cloud access grants or cipher configurations. -

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,... -

LibPDF
A modern PDF library for TypeScript
...Unlike many existing JavaScript PDF libraries, it emphasizes lenient parsing that can gracefully handle malformed structures and fallback strategies where typical parsers fail, making it useful for production environments that encounter unpredictable file formats. The library offers full read and write manipulation, including support for encryption with RC4 and modern AES cipher suites, form filling and flattening, digital signature creation and verification, page merging/splitting, rich text extraction with layout information, and font embedding with subsetting. -

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). -
