CrococryptMirror is an encryption tool which mirrors complete folders to encrypted folders. The encryption algorithms that are used are AES and Twofish (256 bits, cascading). The keyfile is secured by a password using PKCS #5 (PBKDF2) with a SHA512/Whirlpool based HMAC using 100000 iterations and also AES and Twofish. Mirroring can be done manually (on-demand) or by using the sync service which detects directory changes on the fly.
