       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.
