    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...

    Tink

    Tink

    A library that provides cryptographic APIs that are easy and secure

    Cryptography is difficult to get right. With Tink, you can encrypt or sign data with just a few lines of code, with built-in security guarantees to help you avoid pitfalls. Tink adds security protections on top of well known libraries like BoringSSL and Java Cryptography Architecture and shows them right in the interfaces, so auditors and tools can quickly find gaps.
