Create a New Key

> ./crypto_buddy aes key -c aes-256-gcm -e hex
key: 6c68470a7cd089381a006865d1f8cde5ece5ad5301faaff3bc01bcc4bf19c98b

Encrypt

Using the key created above, use it to encrypt a password. The output will be an encoded string.

\> ./crypto_buddy aes encrypt                                                 \
          -c aes-256-gcm                                                      \
          -k 6c68470a7cd089381a006865d1f8cde5ece5ad5301faaff3bc01bcc4bf19c98b \
          --text 'fat cats gobble dogs and eat bats'

$aes-256-gcm$hex$7aeefe6389bc163187716269$c21071c9f1404afb2f7e9975fb6a00db53b442be8a07ec26979c4c2cdb56c15bf97afee3558d25b15b60564eb8bb8ce83e

Decrypt

To decrypt, pass in the original key along with the encoded text from the encrypt operation.

\> ./crypto_buddy aes decrypt \
            -k 6c68470a7cd089381a006865d1f8cde5ece5ad5301faaff3bc01bcc4bf19c98b 
            -m '$aes-256-gcm$hex$7aeefe6389bc163187716269$c21071c9f1404afb2f7e9975fb6a00db53b442be8a07ec26979c4c2cdb56c15bf97afee3558d25b15b60564eb8bb8ce83e'
