Field Detail

<static> KJUR.asn1.cms.SignerInfo.setForContentAndHash

set ContentType/MessageDigest/DigestAlgorithms for SignerInfo/SignedData This method will specify following fields by a parameters:

add ContentType signed attribute by encapContentInfo
add MessageDigest signed attribute by encapContentInfo and hashAlg
add a hash algorithm used in MessageDigest to digestAlgorithms field of SignedData
set a hash algorithm used in MessageDigest to digestAlgorithm field of SignerInfo

Argument 'params' is an associative array having following elements:

eciObj - KJUR.asn1.cms.EncapsulatedContentInfo object
sdObj - KJUR.asn1.cms.SignedData object (Option) to set DigestAlgorithms
hashAlg - string of hash algorithm name which is used for MessageDigest attribute

some of elements can be omited.

sd = new KJUR.asn1.cms.SignedData();
signerInfo.setForContentAndHash({sdObj: sd,
                                 eciObj: sd.dEncapContentInfo,
                                 hashAlg: 'sha256'});
