Method Detail

checkAttachedSignature

List<SignatureInformations> checkAttachedSignature(byte[] signedData)

Check a digital signature with attached content, informed by parameter signedData

Parameters:

signedData - attached signature to be checked

Returns:

List<SignatureInformations> list of signature information

checkDetachedSignature

List<SignatureInformations> checkDetachedSignature(byte[] content,
                                                   byte[] signedData)

Check an digital detached signature, informed by parameter signedData and it's content

Parameters:

content - content to be checked

signedData - detached signature

Returns:

List<SignatureInformations> list of signature information

checkSignatureByHash

List<SignatureInformations> checkSignatureByHash(String digestAlgorithmOID,
                                                 byte[] calculatedHashContent,
                                                 byte[] signedData)

Check a digital detached signature, informed by parameter signedData, based on calculated hash from content

Parameters:

digestAlgorithmOID - OID of algorithm used to calculate a hash from content (ex: 2.16.840.1.101.3.4.2.1 )

calculatedHashContent - calculated hash

signedData - detached signature

Returns:

List<SignatureInformation> list of signature information
