XBCRYPT(1)                    Percona XtraBackup                    XBCRYPT(1)

NAME
       xbcrypt - Percona xbcrypt Documentation

       To support encryption and decryption of the backups, a new tool xbcrypt
       was introduced to Percona XtraBackup.

       Percona XtraBackup 8.0.28-20 implements the XBCRYPT_ENCRYPTION_KEY
       environment variable. The variable is only used in place of the
       --encrypt_key=name option. You can use the environment variable or
       command line option. If you use both, the command line option takes
       precedence over the value specified in the environment variable.

       This utility has been modeled after xbstream_binary to perform
       encryption and decryption outside of Percona XtraBackup. xbcrypt has
       following command line options:

       -d, --decrypt
              Decrypt data input to output.

       -i, --input=name
              Optional input file. If not specified, input will be read from
              standard input.

       -o, --output=name
              Optional output file. If not specified, output will be written
              to standard output.

       -a, --encrypt-algo=name
              Encryption algorithm.

       -k, --encrypt-key=name
              Encryption key.

       -f, --encrypt-key-file=name
              File which contains encryption key.

       -s, --encrypt-chunk-size=#
              Size of working buffer for encryption in bytes. The default
              value is 64K.

       --encrypt-threads=#
              This option specifies the number of worker threads that will be
              used for parallel encryption/decryption.

       -v, --verbose
              Display verbose status output.
