Method Detail

setRevocable

public void setRevocable(boolean isCritical,
                         boolean isRevocable)

setExportable

public void setExportable(boolean isCritical,
                          boolean isExportable)

setTrust

public void setTrust(boolean isCritical,
                     int depth,
                     int trustAmount)
Add a TrustSignature packet to the signature. The values for depth and trust are largely installation dependent but there are some guidelines in RFC 4880 - 5.2.3.13.

Parameters:
isCritical - true if the packet is critical.
depth - depth level.
trustAmount - trust amount.

setKeyExpirationTime

public void setKeyExpirationTime(boolean isCritical,
                                 long seconds)
Set the number of seconds a key is valid for after the time of its creation. A value of zero means the key never expires.

Parameters:
isCritical - true if should be treated as critical, false otherwise.
seconds -

setSignatureExpirationTime

public void setSignatureExpirationTime(boolean isCritical,
                                       long seconds)
Set the number of seconds a signature is valid for after the time of its creation. A value of zero means the signature never expires.

Parameters:
isCritical - true if should be treated as critical, false otherwise.
seconds -

setSignatureCreationTime

public void setSignatureCreationTime(boolean isCritical,
                                     java.util.Date date)
Set the creation time for the signature.

Note: this overrides the generation of a creation time when the signature is generated.


setPreferredHashAlgorithms

public void setPreferredHashAlgorithms(boolean isCritical,
                                       int[] algorithms)

setPreferredSymmetricAlgorithms

public void setPreferredSymmetricAlgorithms(boolean isCritical,
                                            int[] algorithms)

setPreferredCompressionAlgorithms

public void setPreferredCompressionAlgorithms(boolean isCritical,
                                              int[] algorithms)

setKeyFlags

public void setKeyFlags(boolean isCritical,
                        int flags)

setSignerUserID

public void setSignerUserID(boolean isCritical,
                            java.lang.String userID)

setEmbeddedSignature

public void setEmbeddedSignature(boolean isCritical,
                                 PGPSignature pgpSignature)
                          throws java.io.IOException
Throws:
java.io.IOException

setPrimaryUserID

public void setPrimaryUserID(boolean isCritical,
                             boolean isPrimaryUserID)

setNotationData

public void setNotationData(boolean isCritical,
                            boolean isHumanReadable,
                            java.lang.String notationName,
                            java.lang.String notationValue)
