• Creating an encrypted backup of a file
• Decrypting a file that was backed up

Advanced Options and Flags

GPGCompose offers a variety of advanced options and flags that can be used to customize the encryption process. Here are some of the most common options and flags:

• -e: Encrypt a file
• -d: Decrypt a file
• -a: Use ASCII-armored output
• -b: Use binary output
• -k: Use a specific key for encryption/decryption
• -p: Use a passphrase for encryption/decryption
• -r: Recursively encrypt/decrypt files in a directory
• -v: Verbose output

Examples in Real-World Scenarios

GPGCompose can be used in a variety of real-world scenarios. Here are some examples:

• Encrypting sensitive data before sending it over the internet
