XBCRYPT(1)

🎀 NAME 🎀

okay so hi bestie 💖 meet xbcrypt, aka the Percona xbcrypt documentation, and she is that girl. To support encryption and decryption of the backups, a whole new tool called xbcrypt got introduced into Percona XtraBackup. she's the glow-up era of your backup game, fr fr ✨

Percona XtraBackup 8.0.28-20 implements the XBCRYPT_ENCRYPTION_KEY environment variable, and she's kind of a big deal. Important tho: that variable is only used in place of the --encrypt_key=name option. So you can use the environment variable or the command line option — either one works. But if you use both? 🫢 the command line option takes precedence over the value specified in the environment variable. main character energy, periodt 👑

This utility has been modeled after xbstream_binary so she can perform encryption and decryption outside of Percona XtraBackup. literally the whole point. and xbcrypt has the following command line options 🌸

✨ OPTIONS ✨

• -d, --decrypt — decrypt data input to output. that's it, that's the vibe 🔓
• -i, --input=name — optional input file. if you don't specify one, input will be read from standard input 🎀
• -o, --output=name — optional output file. if you don't specify one, output will be written to standard output 🌈
• -a, --encrypt-algo=name — the encryption algorithm 🧚
• -k, --encrypt-key=name — the encryption key 🔑
• -f, --encrypt-key-file=name — the file which contains the encryption key 📁
• -s, --encrypt-chunk-size=# — size of the 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. yes bestie, parallel 💅🔥
• -v, --verbose — display verbose status output. for when you Need To Know Everything 👀
