PGPKey Type
This container represents a PGP key.
Remarks
OpenPGP standard supports several types of keys. In our days, a typical OpenPGP keypair actually consists of two cryptographic keys: a primary key and a subkey. The primary key is normally used for signing, while the subkey is used for encryption.
While it is typical for PGP environments to use a primary key/subkey bundle, this is not a must. Sometimes you may come across standalone keys (mainly when dealing with older implementations), as well as whole key trees, each of those carrying a bunch of differently-purposed subkeys bound to the same primary key.
Algorithm-wise, OpenPGP keys also differ. Generally speaking, OpenPGP supports the following public key algorithms: RSA, Elgamal (often incorrectly referred to as DH), DSA, ECDH and ECDSA. When it comes to primary key/subkey bundles, DSA/Elgamal, RSA/RSA and ECDSA/ECDH pairs are typically used. Although there's no restriction on algorithm bundles, and, e.g. a ECDSA/Elgamal key bundle is perfectly possible, such combination is rarely used in practice.
A typical OpenPGP key is associated with some kind of user ID (Username). It is normally represented with a user's e-mail address, while in theory can be any piece of text. The secret part of the OpenPGP keypair is protected with a password (Passphrase).

Bool (read-only)
Default Value: False
Returns True if this key can be used for encryption.
canSign
Bool (read-only)
Default Value: False
Returns True if this key can be used for signing.
curve
String (read-only)
Default Value: ""
Indicates the elliptic curve associated with a EC key.
Supported values:
SB_PGP_CURVE_P256 | P256 | |
SB_PGP_CURVE_P384 | P384 | |
SB_PGP_CURVE_P521 | P521 | |

enabled
Bool
Default Value: False
Enables or disables this key for use in encryption or signing operation.
encryptionAlgorithm
String (read-only)
Default Value: "AES128"
Indicates the symmetric algorithm used to encrypt the secret key.
handle
Int64
Default Value: 0
Allows to get or set a 'handle', a unique identifier of the underlying property object. Use this property to assign objects of the same type in a quicker manner, without copying them fieldwise.
When you pass a handle of one object to another, the source object is copied to the destination rather than assigned. It is safe to get rid of the original object
after such operation.
pdfSigner.setSigningCertHandle(certMgr.getCertHandle());
isPublic
Bool (read-only)
Default Value: False
Returns True if this key is a public key, and False otherwise.
isSecret
Bool (read-only)
Default Value: False
Returns True if this key is a secret key, and False otherwise.
isSubkey
Bool (read-only)
Default Value: False
Returns True if this key is a subkey of another key, and False otherwise.
keyFP
String (read-only)
Default Value: ""
The 20-byte fingerprint (hash value) of this key.
KeyFP could be used to distinguish two keys with the same KeyID.
keyID
String (read-only)
Default Value: ""
Contains a 8-byte key identifier.
It is quite rare that IDs of two keys collide. If that happens, their fingerprints (KeyFP) can be used for distinguish between the keys. Please note that many PGP implementations show only 4 lowest bytes of the KeyID to the user.
passphrase
String
Default Value: ""
The key protection password.
passphraseValid
Bool (read-only)
Default Value: False
Use this property to check whether the specified is valid and can be used to unlock the secret key.
primaryKeyID
String (read-only)
Default Value: ""
If this key is a subkey ( returns True), this property contains the identifier of the subkey's primary key.
protection
PGPProtectionTypes (read-only)
Default Value: 0
Specifies the level of protection applied to the secret key.
Allowed values:
pptNone | 0 | Key is not encrypted |

Default Value: ""
Specifies the asymmetric algorithm of the key.
qBits
Int32 (read-only)
Default Value: 0
The length of the DSA Q (legitimate range: 160-512).
This parameter corresponds to the hash algorithm used with the key. For example, if the value of Q is 256, SHA-256 will be used.
timestamp
String (read-only)
Default Value: ""
Use this property to check the time the key was generated. The date and time are stored and retrieved in Universal Coordinate Time (UTC).
username
String (read-only)
Default Value: ""
Specifies the name of the user bound to this key.
The PGP username is typically represented with a full name and an email address, but generally can be any non-empty string.

Int32 (read-only)
Default Value: 0
Indicates the key version.
The key version refers to the version of the public-key packet format as defined in RFC 4880.
