This property specifies the elliptic curve used in the ECDSA or EdDSA key. This property is only applicable if PublicKeyAlgorithm is ECDSA or EdDSA. Possible values are:

The date when this key becomes valid. Prior to this it is not valid. The following is an example of a valid encoded date:

23-Jan-2000 15:00:00.

The key. This property is used to assign a specific key. The UserId properties may also be used to specify a key.

The key. This property is used to assign a specific key. The UserId properties may also be used to specify a key.

The date the key expires. After this date the key will no longer be valid. The following is an example of a valid encoded date:

23-Jan-2001 15:00:00.

The hex-encoded, 20-byte fingerprint of the key.

This is in the form:

5E70662EA810E768391A2FE8F7B7D49C89C9D7B1

The hex-encoded, 4-byte key Id. It is same as last 4 bytes of Fingerprint.

This is in the form:

89C9D7B1

The location of the keyring.

If the keyring is stored in a directory, set this property to the directory. The directory must contain the files "secring.gpg" and "pubring.gpg". A keyring may also be stored in a single file. If the keyring is a file this property should be set to the path of the file.

When This property is set the component will read the keyring and populate the Key* properties with the first key found in the keyring. Set UserId to select a different key in the current keyring.

If the specified key has alternate user Ids associated with it, this property returns a comma-separated list of the other user Ids.

The passphrase for the key's secret key (if any). This must be specified before operations requiring the secret key are attempted. The passphrase may be supplied in this property or through the KeyPassphrase event, which will fire when a passphrase is required.

The passphrase is required when using the following methods in KeyMgr:

• AddUserId
• SignUserId
• ChangeExpirationDate
• ChangePassphrase

When using the OpenPGP component, or an email-based component, the following methods require a passphrase for the key:

• Decrypt
• Sign
• SignAndEncrypt

The public key of the key. The key is provided as ASCII armored data.

A text description of the public key algorithm of the key. Possible values are:

• RSA
• DSA
• ECDSA
• EdDSA
• RSA-Legacy

The length of the public key in bits. Common values are 512, 1024, and 2048.

If the PublicKeyAlgorithm property is ECDSA or EcDSA the length of the public key is determined by the Curve. Possible lenghts are:

Whether or not the key is revoked.

The secret key of the key (if available). The key is provided as ASCII armored data.

Whether or not a secret key is available for the selected key.

A text 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

Flags that show the intended use for the key. The default value is 0x0F. The value of UsageFlags is a combination of the following flags:

Please refer to the Usage property for a text representation of UsageFlags.

The user Id of the key. When a key is loaded this property is populated with the user Id associated with the key. This property may be set to load a key from the Keyring. When this property is set the component will search the Keyring for a key associated with the UserId specified.

When loading a key with multiple user Ids, this property will be populated with the UserId that was most recently added to the key. To discover all of the UserIds associated with a key query this property and OtherUserIds after loading the key.

The UserId format is:

FirstName LastName (Comment) <Email>

When using this property to select a key you may also specify the key's Id, or any of its subkeys' Ids, instead of a user Id. The component will then search for a key with a matching Id. This is helpful in situations where you do not have the UserId but still need to load the key, such as within the OpenPGP component's RecipientInfo event.
