FortressCLI

Fortress is an open source file encryption command-line tool based on the AES-256 encryption standard.

It implements the Cipher Block Chaining Mode as described in the NIST Special Publication 800-38A Section 6.2.

Encrypt/Decrypt a file

To encrypt/decrypt files, the following parameters should be used when running fortress-cli:

./path-to/fortress-cli  <encrypt/decrypt>  filename_1  filename_2  passphrase

For file encryption:

"filename_1" is the file to be encrypted
"filename_2" is the name of the encrypted output, a BIN format is recommmended e.g. "output.bin"
The last parameter is the passphrase used to encrypt the file

For file decryption:

"filename_1" is the name of the decrypted output to be generated
"filename_2" is the name of the encrypted input
The last parameter is the passphrase used to decrypt the file (it must match the original encryption passphrase for successful decryption)

All file names should end with a format e.g. "name.format"

Features to be implemented:

Integrity checks: give option to check integrity of files with checksum and signatures
Progress indicator while encrypting/decrypting
File Shredder: option to delete original file after encryption
Cross-platform compatibility
Parallel processing
Automated tests
Examples and docs

Steganography support
Time based encryption (give users the option to specify a time window in which the file can be decrypted)
Hardware acceleration
Biometric key generation
