AS-ARC6 1.10
Screenshot of AS-ARC6 1.10

A command line program for encryption and decryption of files. The program uses a 512-bit ARC6-64/96/64 (in CTR mode [1]).

The program uses a key strengthening algorithm [2], this increases the security.

The program stores an encrypted checksum [3] of the original file, which is verified at decryption.

The program delivers an ErrorLevel code [4] which indicates success (0) or failure (1).

The speed is measured and the program will display the results for you when it's done.

Use the parameter "-NoPercent" to display the number of Bytes that has been processed instead of percent.

Speed Reference: Approximately 24 MB/sec. (Intel Core i3-9100) [5]

Important information: Save the downloaded program if you have information encrypted with it. I do not guarantee compatibility between different versions/revisions of the program.

[1] Counter mode, a block cipher mode used to make a stream cipher of a block cipher. In this program, a 256-bit random nonce is used, which is fetched from Microsoft Crypto API. (RANDOM.DLL / RANDOM-X86.DLL)
[2] The key strengthening algorithm is using SHA3-512 and executes 131,072 times. (KSA.DLL / KSA-X86.DLL)
[3] The encrypted checksum is a CRC-64-ECMA.
[4] The ErrorLevel code can be useful when calling from batch files or other programs.
[5] The speed reference is measured under good conditions, a fast disk and a pretty large file.
