Method Detail

<static> {KJUR.asn1.cms.SignedData} KJUR.asn1.cms.CMSUtil.newSignedData(param)

generate SignedData object specified by JSON parameters This method provides more easy way to genereate CMS SignedData ASN.1 structure by JSON data.
Here is major parameters:

content - to specify data to be signed in eContent field.
certs - a list of certificate PEM strings to specify certificate field
detached - 'true' or 'false' to specify detached signature or not. The default is 'false'
signerInfos - array of signerInfo parameters. SignerInfo parameters listed here:
- hashAlg - string of messageDigest hash algorithm name
- sAttr - list of signedAttribute parameters
- signerCert - string of signer certificate PEM
- sigAlg - string of signature algorithm name
- signerPrvKey - string of PEM signer private key

var sd = KJUR.asn1.cms.CMSUtil.newSignedData({
  content: {str: "jsrsasign"},
  certs: [certPEM],
  detached: false,
  signerInfos: [{
    hashAlg: 'sha256',
    sAttr: {
      SigningTime: {}
      SigningCertificateV2: {array: [certPEM]},
    },
    signerCert: certPEM,
    sigAlg: 'SHA256withRSA',
    signerPrvKey: prvPEM
  }]
});

Parameters:
{Array} param: JSON parameter to generate CMS SignedData

Returns:: {KJUR.asn1.cms.SignedData} object just generated

<static> {Object} KJUR.asn1.cms.CMSUtil.verifySignedData(param)

verify SignedData specified by JSON parameters This method provides validation for CMS SignedData. Following parameters can be applied:

cms - hexadecimal data of DER CMS SignedData (aka. PKCS#7 or p7s)

KJUR.asn1.cms.CMSUtil.verifySignedData({ cms: "3082058a..." }) 
→
{
  isValid: true,
  parse: ... // parsed data
  signerInfos: [
    {
    }
  ]
}

Parameters:
{Array} param: JSON parameter to verify CMS SignedData

Since:: jsrsasign 8.0.4 asn1cms 1.0.5

Returns:: {Object} JSON data as the result of validation
