keyctl

Manipulate the Linux kernel keyring.

• List keys in a specific keyring:

keyctl list {target_keyring}

• List current keys in the user default session:

keyctl list {@us}

• Store a key in a specific keyring:

keyctl add {type_keyring} {key_name} {key_value} {target_keyring}

• Store a key with its value from standard input:

echo -n {key_value} | keyctl padd {type_keyring} {key_name} {target_keyring}

• Put a timeout on a key:

keyctl timeout {key_name} {timeout_in_seconds}

• Read a key and format it as a hex-dump if not printable:

keyctl read {key_name}

• Read a key and format as-is:

keyctl pipe {key_name}

• Revoke a key and prevent any further action on it:

keyctl revoke {key_name}
