mage is a simple program for encrypting and decrypting multiple files with age
using a common passphrase.
Simply run mage followed by 1 or more files:
mage path/to/file1.txt etc/file2.conf
mage path/to/file1.txt.age etc/file2.conf.age
If all files end with .age, they will be decrypted. If none of the files end
with .age, they will be encrypted. It is not allowed to specify a mixture of
unencrypted and encrypted files. You will be prompted to enter the passphrase.
Input files will be deleted after encryption/decryption.
