SubkeyList Event
Fires once for each subkey listed when ListSubkeys is called.
Syntax
keymgr.on('SubkeyList', [callback])
Callback
The 'callback' is called when the 'SubkeyList' event is emited.
function(e){ }
The argument 'e' has the following properties:
e.keyId e.fingerprint e.publicKeyAlgorithm e.publicKeyLength e.curve e.usageFlags e.usage e.effectiveDate e.expirationDate e.revoked
Remarks
This event fires once for each subkey when ListSubkeys is called.
KeyId is the hex-encoded, 4- or 8-byte Id of the key. It is the same as the last 4 or 8 bytes of the Fingerprint. For instance:
BF52A0AB
Fingerprint holds the hex-encoded, 20-byte fingerprint of the key. This is in the form:
5E70662EA810E768391A2FE8F7B7D49C89C9D7B1
PublicKeyAlgorithm is the public key algorithm. Possible values are:
- RSA
- Elgamal
- ECDH (Only used with ECDSA and EdDSA keys)
PublicKeyLength is the length of the public key. Common values are 512, 1024, and 2048.
Curve is the curve used by the key when PublicKeyAlgorithm is ECDH. Possible values are:
Value | Description |
secp256r1 | NIST curve P-256 |
secp384r1 | NIST curve P-384 |
secp521r1 | NIST curve P-521 |
Curve25519 | Curve25519 |
Ed25519 | Ed25519 |
Usage is the textual description of UsageFlags.
The value will be of one or more of the following strings, separated by commas:
- Certifying Other Certificates
- Signing Emails and Files
- Encrypting Emails and Files
- Split Key
- Authenticate Against Servers
- Group Key
UsageFlags is an integer flag that shows the intended use for the key. The value is a combination of the following flags:
0x01 | This key may be used to certify other keys. |
0x02 | This key may be used to sign data. |
0x0C | This key may be used to encrypt communications and encrypt storage. |
0x10 | The private component of this key may have been split by a secret-sharing mechanism. |
0x20 | This key may be used for authentication. |
0x80 | The private component of this key may be in the possession of more than one person. |
EffectiveDate is the date when this key became valid. The following example illustrates the format of an encoded date:
23-Jan-2000 15:00:00.
ExpirationDate is the date the key expires. After this date the key will no longer be valid. The following example illustrates the format of an encoded date:
23-Jan-2000 15:00:00.If the ExpirationDate is not populated this indicates that the key never expires.
Revoked Indicates whether the subkey is revoked or not.
