Class RSASSAPSSMechanismParams

Namespace
iText.Signatures
Assembly
itext.sign.dll

Encode the signer's parameters for producing an RSASSA-PSS signature.

public class RSASSAPSSMechanismParams : IApplicableSignatureParams, ISignatureMechanismParams
Inheritance
RSASSAPSSMechanismParams
Implements
Inherited Members

Remarks

Encode the signer's parameters for producing an RSASSA-PSS signature. Note that this class is intended for use in the signing process only, so it does not need to be able to represent all possible parameter configurations; only the ones we consider reasonable. For the purposes of this class, the mask generation function is always MGF1, and the associated digest function is the same as the digest function used in the signing process.

Constructors

RSASSAPSSMechanismParams(IDerObjectIdentifier, int, int)

Instantiate RSASSA-PSS parameters with MGF1 for a given digest algorithm OID, salt length and trailer field value.

public RSASSAPSSMechanismParams(IDerObjectIdentifier digestAlgoOid, int saltLen, int trailerField)

Parameters

digestAlgoOid IDerObjectIdentifier

the digest algorithm OID that will be used for both the digest and MGF

saltLen int

the salt length

trailerField int

the trailer field

Fields

DEFAULT_TRAILER_FIELD

Default value of the trailer field parameter.

public const int DEFAULT_TRAILER_FIELD = 1

Field Value

int
