This class provides utility static methods for CSR/PKCS#10. Here is a list of methods:

Method Detail

<static> {Object} KJUR.asn1.csr.CSRUtil.getInfo(sPEM)

get field values from CSR/PKCS#10 PEM string
This method parses PEM CSR/PKCS#1 string and retrieves subject name and public key. Following parameters are available in the resulted JSON object.

subject.name - subject name string (ex. /C=US/O=Test)
subject.hex - hexadecimal string of X.500 Name of subject
pubkey.obj - subject public key object such as RSAKey, KJUR.crypto.{ECDSA,DSA}
pubkey.hex - hexadecimal string of subject public key

o = KJUR.asn1.csr.CSRUtil.getInfo("-----BEGIN CERTIFICATE REQUEST...");
console.log(o.subject.name) → "/C=US/O=Test"

Parameters:
{String} sPEM: PEM string of CSR/PKCS#10

Since:: jsrsasign 6.1.3 asn1csr 1.0.1

Returns:: {Object} JSON object with parsed parameters such as name or public key

<static> KJUR.asn1.csr.CSRUtil.newCSRPEM(param)

generate a PEM format of CSR/PKCS#10 certificate signing request This method can generate a CSR certificate signing request by a simple JSON object which has following parameters:

subject - parameter to be passed to KJUR.asn1.x509.X500Name
sbjpubkey - parameter to be passed to KEYUTIL.getKey
sigalg - signature algorithm name (ex. SHA256withRSA)
sbjprvkey - parameter to be passed to KEYUTIL.getKey

// 1) by key object
pem = KJUR.asn1.csr.CSRUtil.newCSRPEM({
  subject: {str: '/C=US/O=Test/CN=example.com'},
  sbjpubkey: pubKeyObj,
  sigalg: "SHA256withRSA",
  sbjprvkey: prvKeyObj
});

// 2) by private/public key PEM 
pem = KJUR.asn1.csr.CSRUtil.newCSRPEM({
  subject: {str: '/C=US/O=Test/CN=example.com'},
  sbjpubkey: pubKeyPEM,
  sigalg: "SHA256withRSA",
  sbjprvkey: prvKeyPEM
});

// 3) with generateKeypair
kp = KEYUTIL.generateKeypair("RSA", 2048);
pem = KJUR.asn1.csr.CSRUtil.newCSRPEM({
  subject: {str: '/C=US/O=Test/CN=example.com'},
  sbjpubkey: kp.pubKeyObj,
  sigalg: "SHA256withRSA",
  sbjprvkey: kp.prvKeyObj
});

// 4) by private/public key PEM with extension
pem = KJUR.asn1.csr.CSRUtil.newCSRPEM({
  subject: {str: '/C=US/O=Test/CN=example.com'},
  ext: [
    {subjectAltName: {array: [{dns: 'example.net'}]}
  ],
  sbjpubkey: pubKeyPEM,
  sigalg: "SHA256withRSA",
  sbjprvkey: prvKeyPEM
});

Parameters:
{Array} param: parameter to generate CSR
