Detailed Description

Implementation of the IExternalSignature interface that can be used when you have a iText.Commons.Bouncycastle.Crypto.IPrivateKey object.

Constructor & Destructor Documentation

PrivateKeySignature() [1/2]

iText.Signatures.PrivateKeySignature.PrivateKeySignature ( IPrivateKey  pk, String  hashAlgorithm  )

inline

Creates a PrivateKeySignature instance.

Parameters

pk	A iText.Commons.Bouncycastle.Crypto.IPrivateKey object.
hashAlgorithm	A hash algorithm (e.g. "SHA-1", "SHA-256",...).
provider	A security provider (e.g. "BC").

PrivateKeySignature() [2/2]

iText.Signatures.PrivateKeySignature.PrivateKeySignature ( IPrivateKey  pk, String  hashAlgorithm, String  signatureAlgorithm, IApplicableSignatureParams @  params  )

inline

Creates a PrivateKeySignature instance.

Parameters

pk	A iText.Commons.Bouncycastle.Crypto.IPrivateKey object.
hashAlgorithm	A hash algorithm (e.g. "SHA-1", "SHA-256",...).
signatureAlgorithm	A signiture algorithm (e.g. "RSASSA-PSS", "id-signedData", "sha256WithRSAEncryption", ...)
provider	A security provider (e.g. "BC").
params	Parameters for using RSASSA-PSS or other algorithms requiring them.
