Returns the IDigest to digest the data imprint

Returns

The IDigest object.

Implemented in iText.Signatures.TSAClientBouncyCastle.

GetTimeStampToken()

byte [] iText.Signatures.ITSAClient.GetTimeStampToken

(

byte[]

imprint

)

Returns RFC 3161 timeStampToken.

Parameters

imprint

byte[] - data imprint to be time-stamped

Returns

byte[] - encoded, TSA signed data of the timeStampToken

Implemented in iText.Signatures.TSAClientBouncyCastle.

GetTokenSizeEstimate()

int iText.Signatures.ITSAClient.GetTokenSizeEstimate

(

)

Get the time stamp estimated token size.

Get the time stamp estimated token size. Implementation must return value large enough to accommodate the entire token returned by GetTimeStampToken(byte[]) prior to actual GetTimeStampToken(byte[]) call.

Returns

an estimate of the token size

Implemented in iText.Signatures.TSAClientBouncyCastle.
