FineCrypt - Version 2.0 With FineCrypt you can create encrypted self-extracting executables which you can send through Internet and decrypt them without FineCrypt. FineCrypt can encipher files in two ways: with a user password or with a user key. You can choose for the purposes of enciphering any of five encryption algorithms and any of four encryption modes. The program has a key management feature developed and patented by Crypto Systems. With the File Statistics feature, you can even check the quality of enciphering performed by other encryption software.
