Method Detail

checkAndFixParam()

fix fields before ASN.1 encode
Update following values of "params" property as defined in RFC 5652:

set "digestAlgorithms" field of "signedData" by signerInfos
set all "contentType" signed attribute value to the same value of eContent
set all "messageDigest" signed attribute value to hash value of eContent contents value
all signerInfo version by their fields
signedData version by their fields

In general, you don't need to call this method. It will be called automatically when getEncodedHex() method is called.
NOTE: If you don't want to do such property value update, set "params.fixed" property to "true".

{Object} getContentInfo()

get CotentInfo ASN.1 object concluding CMS SignedData
This method returns a KJUR.asn1.ASN1Object of ContentInfo concludes SignedData.

sd = new KJUR.asn1.cms.SignedData({...});
sd.getContentInfo();

Returns:: {Object} ContentInfo of SigneData as KJUR.asn1.ASN1Object

See:: KJUR.asn1.cms.ContentInfo

{String} getContentInfoEncodedHex()

get hex of entire ContentInfo of CMS SignedData
This method returns a hexadecimal string of ContentInfo concludes SignedData.

sd = new KJUR.asn1.cms.SignedData({...});
sd.getContentInfoEncodedHex() &rarr "3082..."

Returns:: {String} hexadecimal string of entire ContentInfo of CMS SignedData

See:: KJUR.asn1.cms.SignedData#getContentInfo; KJUR.asn1.cms.ContentInfo
