The xbcrypt binary overview¶
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 The xbstream binary to perform encryption and decryption outside of Percona XtraBackup. `
For more details on the command-line options, see xbcrypt command-line options
