seKeyExpirationTime = 7	seKeyExpirationTime	Validity period of the key. The corresponding class is TElPGPKeyExpirationTimeSignatureSubpacket
sePrefferedSymAlg = 8	sePrefferedSymAlg	Symmetric algorithm numbers that indicate which algorithms the key holder prefers to use. The corresponding class is TElPGPPreferredSymmetricAlgorithmsSignatureSubpacket
seRevocationKey = 9	seRevocationKey	Authorizes the specified key to issue revocation signatures for this key. The corresponding class is TElPGPRevocationKeySignatureSubpacket
seIssuerKeyID = 10	seIssuerKeyID	OpenPGP key ID of the key issuing the signature. The corresponding class is TElPGPIssuerKeyIDSignatureSubpacket
seNotationData = 11	seNotationData	Describes a ‘notation’ on the signature that the issuer wishes to make. The corresponding class is TElPGPNotationDataSignatureSubpacket
sePrefferedHashAlg = 12	sePrefferedHashAlg	Message digest algorithm numbers that indicate which algorithms the key holder prefers to receive. The corresponding class is TElPGPPreferredHashAlgorithmsSignatureSubpacket
sePrefferedComprAlg = 13	sePrefferedComprAlg	Compression algorithm numbers that indicate which algorithms the key holder prefers to use. The corresponding class is TElPGPPreferredCompressionAlgorithmsSignatureSubpacket
seKeyServerPreferences = 14	seKeyServerPreferences	A list of flags that indicate preferences that the key holder has about how the key is handled on a key server. The corresponding class is TElPGPKeyServerPreferencesSignatureSubpacket
sePrefferedKeyServer = 15	sePrefferedKeyServer	A URL of a key server that the key holder prefers be used for updates. The corresponding class is TElPGPPreferredKeyServerSignatureSubpacket
sePrimaryUserID = 16	sePrimaryUserID	A flag in a user id's self signature that states whether this user id is the main user id for this key. The corresponding class is TElPGPPrimaryUserIDSignatureSubpacket
sePolicyURL = 17	sePolicyURL	Contains a URL of a document that describes the policy that the signature was issued under. The corresponding class is TElPGPPolicyURLSignatureSubpacket
seKeyFlags = 18	seKeyFlags	Flags may appear in self-signatures or in certification signatures. The corresponding class is TElPGPKeyFlagsSignatureSubpacket
seSignerUserID = 19	seSignerUserID	Allows a keyholder to state which user id is responsible for the signing. The corresponding class is TElPGPSignersUserIDSignatureSubpacket
seReasonForRevocation = 20	seReasonForRevocation	Describes the reason why the key or certificate was revoked. The corresponding class is TElPGPReasonForRevocationSignatureSubpacket

Return value

True if the extension was removed successfully.
False otherwise.

Description

Use this method to remove the extension. If extension type is specified, then Index parameter means an index among extensions of this type. Otherwise it means an index among all extensions.
