Guys, I am looking for reliable, ideally open source file encryption software that can encrypt files with cascade encryption algorithms, such as AES-Twofish-Serpent. The only ones that I know of for sure are VeraCrypt (and the abandoned TrueCrypt). It appears PeaZip also implemented cascading encryption algorithms in its most recent version v6.10: ARC FreeARC ARC format implementing encryption scheme that supports AES256, AES contest finalists Twofish256 and Serpent256 algorithms, and classic Blowfish algorithm PEA PeaZip's native .pea file format, supporting AES, Serpent and Twofish (128 and 256 bit) EAX-mode authenticated encryption, enforcing cryptographically strong data secrecy and verifiable authenticity. Any other such software that you could think of, please share it here. Considering the ever increasing computing ability of modern hardware (CUP/GPU, Cloud computing), multiple encryption algorithms don't appear to be an overkill nowadays.
