NAME

       affcrypto - handle encryption issues


SYNOPSIS

       affcrypto [options] filename.aff [filename2.aff ... ]


DESCRIPTION

       Command for dealing with encryption issues.

       This file is part of the AFFLIBv3, that provides AFF.

       AFF  is  an  open  and  extensible file format to store disk images and
       associated metadata. It is useful in  several  scenaries,  as  computer
       forensics investigations.


OPTIONS

       General options:

              -j     Just print the number of encrypted segments.

              -J     Just print the number of unencrypted segments.

              -x     Output in XML.

       Data conversion options:

              -e     Encrypt the unencrypted non-signature segments.

              -d     Decrypt the encrypted non-signature segments.

              -r     Change passphrase (take old and new from stdin).

              -O <old>
                     Specify an old passphrase.

              -N <new>
                     Specify new passphrase.

              -K <mykey.key>
                     Specifies  a  private  keyfile  for unsealing (may not be
                     repeated).

              -C <mycert.crt>
                     Specifies  a  certificate  file  for  sealing   (may   be
                     repeated).

              -S     Add   symmetric   encryptiong   (passphrase)   to  AFFILE
                     encrypted with public key (requires a private key  and  a
                     specified passphrase).

              -A     Add  asymmetric  encryption  to a AFFILE encrypted with a
                     passphrase (requires a certificate file spcified with the
                     -C option).

       Password Cracking Options:

              -f <file>
                     Crack passwords but read them from file.

              -k     Attempt to crack passwords by reading a list of passwords
                     from ~/.affpassphrase.

              -p <passphrase>
                     Checks to see if passphrase  is  the  passphrase  of  the
                     file. Exit code is 0 if yes and -1 if not.

       Debugging:

              -D     debug; print out each key as it is tried.

              -l     List the installed hash and encryption algorithms.

              -V     Just print the version number and exit.


NOTES

       This program ignores these environment variables:

              o  AFFLIB_PASSPHRASE

              o  AFFLIB_PASSPHRASE_FILE

              o  AFFLIB_PASSPHRASE_FD

              o  AFFLIB_DECRYPTING_PRIVATE_KEYFILE


EXAMPLE

       Print if each file is encrypted or not:

           $ affcrypto filename.aff filename2.aff
