VeraCrypt is a free disk encryption software brought to you by IDRIX and that is based on TrueCrypt . It adds enhanced security to the algorithms used for system and partitions encryption making it immune to new developments in brute-force attacks. For example, when the system partition is encrypted, TrueCrypt uses PBKDF2-RIPEMD160 with 1000 iterations whereas in VeraCrypt we use 327670.
- TrueCrypt was discontinued in mysterious circumstances. The code was taken forward by VeraCrypt. It is open source and some security vulnerabilities have been fixed since the TrueCrypt days. It's a great app for creating encrypted containers or encrypting whole drives. Backwards compatible with TrueCrypt. Truly excellent software.
- Open source fork of TrueCrypt. And most important - it's still developed, unlike TrueCrypt.
- It carries forward the classic TrueCrypt UI, which means that any TrueCrypt user can use it easily.
