/**
* kjur's ASN.1 class for RFC 5126 CAdES long term signature
* <p>
* This name space provides
* <a href="https://tools.ietf.org/html/rfc5126">RFC 5126
* CAdES(CMS Advanced Electronic Signature)</a> generator.
*
* <h4>SUPPORTED FORMATS</h4>
* Following CAdES formats is supported by this library.
* <ul>
* <li>CAdES-BES - CAdES Basic Electronic Signature</li>
* <li>CAdES-EPES - CAdES Explicit Policy-based Electronic Signature</li>
* <li>CAdES-T - Electronic Signature with Time</li>
* </ul>
* </p>
*
* <h4>PROVIDED ATTRIBUTE CLASSES</h4>
* <ul>
* <li>{@link KJUR.asn1.cades.SignaturePolicyIdentifier} - for CAdES-EPES</li>
* <li>{@link KJUR.asn1.cades.SignatureTimeStamp} - for CAdES-T</li>
* <li>{@link KJUR.asn1.cades.CompleteCertificateRefs} - for CAdES-C(for future use)</li>
* </ul>
* NOTE: Currntly CAdES-C is not supported since parser can't
* handle unsigned attribute.
*
* <h4>OTHER CLASSES</h4>
* <ul>
* <li>{@link KJUR.asn1.cades.OtherHashAlgAndValue}</li>
* <li>{@link KJUR.asn1.cades.OtherHash}</li>
* <li>{@link KJUR.asn1.cades.OtherCertID}</li>
* <li>{@link KJUR.asn1.cades.CAdESUtil} - utilities for CAdES</li>
* </ul>
*
* <h4>GENERATE CAdES-BES</h4>
* To generate CAdES-BES, {@link KJUR.asn.cades} namespace
* classes are not required and already {@link KJUR.asn.cms} namespace
* provides attributes for CAdES-BES.
* Create {@link KJUR.asn1.cms.SignedData} with following
* mandatory attribute in CAdES-BES:
* <ul>
* <li>{@link KJUR.asn1.cms.ContentType}</li>
* <li>{@link KJUR.asn1.cms.MessageDigest}</li>
* <li>{@link KJUR.asn1.cms.SigningCertificate} or </li>
* <li>{@link KJUR.asn1.cms.SigningCertificateV2}</li>
* </ul>
* CMSUtil.newSignedData method is very useful to generate CAdES-BES.
* <pre>
* sd = KJUR.asn1.cms.CMSUtil.newSignedData({
* content: {str: "aaa"},
* certs: [certPEM],
* signerInfos: [{
* hashAlg: 'sha256',
* sAttr: {SigningCertificateV2: {array: [certPEM]}},
* signerCert: certPEM,
* sigAlg: 'SHA256withRSA',
* signerPrvKey: pkcs8PrvKeyPEM
* }]
* });
* signedDataHex = sd.getContentInfoEncodedHex();
* </pre>
* NOTE: ContentType and MessageDigest signed attributes
* are automatically added by default.
*
* <h4>GENERATE CAdES-BES with multiple signers</h4>
* If you need signature by multiple signers, you can
* specify one or more items in 'signerInfos' property as below.
* <pre>
* sd = KJUR.asn1.cms.CMSUtil.newSignedData({
* content: {str: "aaa"},
* certs: [certPEM1, certPEM2],
* signerInfos: [{
* hashAlg: 'sha256',
* sAttr: {SigningCertificateV2: {array: [certPEM1]}},
* signerCert: certPEM1,
* sigAlg: 'SHA256withRSA',
* signerPrvKey: pkcs8PrvKeyPEM1
* },{
* hashAlg: 'sha1',
* sAttr: {SigningCertificateV2: {array: [certPEM2]}},
* signerCert: certPEM2,
* sigAlg: 'SHA1withRSA',
* signerPrvKey: pkcs8PrvKeyPEM2
* }]
* });
* signedDataHex = sd.getContentInfoEncodedHex();
* </pre>
*
* <h4>GENERATE CAdES-EPES</h4>
* When you need a CAdES-EPES signature,
* you just need to add 'SignaturePolicyIdentifier'
* attribute as below.
* <pre>
* sd = KJUR.asn1.cms.CMSUtil.newSignedData({
* content: {str: "aaa"},
* certs: [certPEM],
* signerInfos: [{
* hashAlg: 'sha256',
* sAttr: {
* SigningCertificateV2: {array: [certPEM]},
* SignaturePolicyIdentifier: {
* oid: '1.2.3.4.5',
* hash: {alg: 'sha1', hash: 'b1b2b3b4b...'}
* },
* },
* signerCert: certPEM,
* sigAlg: 'SHA256withRSA',
* signerPrvKey: pkcs8PrvKeyPEM
* }]
* });
* signedDataHex = sd.getContentInfoEncodedHex();
* </pre>
*
* <h4>GENERATE CAdES-T</h4>
* After a signed CAdES-BES or CAdES-EPES signature have been generated,
* you can generate CAdES-T by adding SigningTimeStamp unsigned attribute.
* <pre>
* beshex = "30..."; // hex of CAdES-BES or EPES data
* info = KJUR.asn1.cades.CAdESUtil.parseSignedDataForAddingUnsigned(beshex);
* // You can refer a hexadecimal string of signature value
* // in the first signerInfo in the CAdES-BES/EPES with a variable:
* // 'info.si[0].sigval'. You need to get RFC 3161 TimeStampToken
* // from a trusted time stamp authority. Otherwise you can also
* // get it by 'KJUR.asn1.tsp' module. We suppose that we could
* // get proper time stamp.
* tsthex0 = "30..."; // hex of TimeStampToken for signerInfo[0] sigval
* si0 = info.obj.signerInfoList[0];
* si0.addUnsigned(new KJUR.asn1.cades.SignatureTimeStamp({tst: tsthex0});
* esthex = info.obj.getContentInfoEncodedHex(); // CAdES-T
* </pre>
* </p>

/**
* parse SignerInfo to add unsigned attributes
* @name parseSignerInfoForAddingUnsigned
* @memberOf KJUR.asn1.cades.CAdESUtil
* @function
* @param {String} hex hexadecimal string of SignerInfo
* @return {Object} associative array of parsed data
* @description
* This method will parse a hexadecimal string of
* SignerInfo to add a attribute
* to unsigned attributes field in a signerInfo field.
* Parsed result will be an associative array which has
* following properties:
* <ul>
* <li>version - hex TLV of version</li>
* <li>si - hex TLV of SignerIdentifier</li>
* <li>digalg - hex TLV of DigestAlgorithm</li>
* <li>sattrs - hex TLV of SignedAttributes</li>
* <li>sigalg - hex TLV of SignatureAlgorithm</li>
* <li>sig - hex TLV of signature</li>
* <li>sigval = hex V of signature</li>
* <li>obj - parsed KJUR.asn1.cms.SignerInfo object</li>
* </ul>
* NOTE: Parsing of unsigned attributes will be provided in the
* future version. That's way this version provides support
* for CAdES-T and not for CAdES-C.
