Usage

Parse the EF.SOD element.

const pem = "MIIHhgYJKoZIhv ... 2lQaWKGlcudYPw==";
const contentInfo = AsnConvert.parse(Convert.FromBase64(pem), ContentInfo);
const signedData = AsnConvert.parse(contentInfo.content, SignedData);
const securityObject = AsnConvert.parse(signedData.encapContentInfo.eContent.single, LDSSecurityObject);

console.log(securityObject);

Output

LDSSecurityObject {
  version: 0,
  hashAlgorithm: DigestAlgorithmIdentifier {
    algorithm: '2.16.840.1.101.3.4.2.1',
    parameters: null
