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  },  dataGroupHashValues: [    DataGroupHash {      dataGroupNumber: 1,      dataGroupHashValue: [Uint8Array]    },    DataGroupHash {      dataGroupNumber: 2,      dataGroupHashValue: [Uint8Array]    },    DataGroupHash {      dataGroupNumber: 3,      dataGroupHashValue: [Uint8Array]    },    DataGroupHash {      dataGroupNumber: 14,      dataGroupHashValue: [Uint8Array]    },    DataGroupHash {      dataGroupNumber: 4,      dataGroupHashValue: [Uint8Array]    }  ]}
