Cipher Information

The cipher-info program describes the format and characteristics of one or more encrypted files. It also reports if the file is incomplete or corrupt. The information returned includes the file name, the protocol, the ID and length of the key, the cipher type, the cipher mode, the hash, ithe entropy type and level, and finally the chunksize and timestamp.

Example Usage

We list a few examples of the cipher-info command here to illustrate its usefulness and ease of use. To get started, lets identify a ciphertext file:

  cipher-info README.cip

returns:
