Member Function Documentation

GetAlgorithm()

static String iText.Signatures.SignatureMechanisms.GetAlgorithm ( String  oid )

inlinestatic

Gets the algorithm name for a certain id.

Parameters

oid	an id (for instance "1.2.840.113549.1.1.1")

Returns

an algorithm name (for instance "RSA")

GetMechanism()

static String iText.Signatures.SignatureMechanisms.GetMechanism ( String  oid, String  digest  )

inlinestatic

Get the signing mechanism name for a certain id and digest.

Parameters

oid	an id of an algorithm
digest	digest of an algorithm

Returns

name of the mechanism

GetSignatureMechanismOid()

static String iText.Signatures.SignatureMechanisms.GetSignatureMechanismOid ( String  signatureAlgorithmName, String  digestAlgorithmName  )

inlinestatic

Attempt to look up the most specific OID for a given signature-digest combination.

Parameters

signatureAlgorithmName	the name of the signature algorithm
digestAlgorithmName	the name of the digest algorithm, if any

Returns

an OID string, or null if none was found.
