While trying to decrypt the secrets in single line command line below I was getting error.
cat file <or echo "whatever"> | base64 --decode | gpg -d
gpg: public key decryption failed: Inappropriate ioctl for device gpg: decryption failed: No secret key
The reason for the key that you have used is password protected. The pipe won’t work with gpg if your key is password protected.
gpg --export "Jayesh-key" | base64 # To get your key gpg --list-keys
In order to get that working. Either you remove pipe in 2 commands.
echo "whatever" | base64 --decode > file.gpg gpg -d file.gpg
or you can modify your key to be without password by providing blank password but thats not a recommended or ideal way.
gpg --edit-key YourKey gpg prmpt > passwd Once it prompts enter existing password to unlock. Once done just enter for blank password. gpg prompt > save
