Generating the client certificate

[lauri-aloauri]

Hello !

For exmaple of openssl command
openssl req -new -newkey rsa:2048 -x509 -sha256 -days 3000 -nodes -out file.cert -keyout file.key -batch -subj "/C=EE/ST=Harjumaa/L=Tallinn/O=Andmevara AS/OU=XXXX"

I tried to achieve the same using the selfigned and experimente with example provided in README.ms (option section):

var pems = selfsigned.generate(null, {
keySize: 2048, // the size for the private key in bits (default: 1024)
days: 30, // how long till expiry of the signed certificate (default: 365)
algorithm: 'sha256', // sign the certificate with specified algorithm (default: 'sha1')
extensions: [{ name: 'basicConstraints', cA: true }], // certificate extensions array
pkcs7: true, // include PKCS#7 as part of the output (default: false)
clientCertificate: true, // generate client cert signed by the original key (default: false)
clientCertificateCN: 'jdoe' // client certificate's common name (default: 'John Doe jdoe123')
});
I removed the lines :
extensions: [{ name: 'basicConstraints', cA: true }], // certificate extensions array
pkcs7: true, // include PKCS#7 as part of the output (default: false)

I used the this inside my javascript:

var pems = selfsigned.generate(null, {
keySize: 2048, // the size for the private key in bits (default: 1024)
days: 30, // how long till expiry of the signed certificate (default: 365)
algorithm: 'sha256', // sign the certificate with specified algorithm (default: 'sha1')
clientCertificate: true, // generate client cert signed by the original key (default: false)
clientCertificateCN: 'jdoe' // client certificate's common name (default: 'John Doe jdoe123')
});

I writed the generted clientcert to file and runned the openssl to view the ceertificate information
openssl x509 -text -noout -in Ilja.cert

From this out there is all as default and these option
keySize: 2048, // the size for the private key in bits (default: 1024)
days: 30, // how long till expiry of the signed certificate (default: 365)
algorithm: 'sha256', // sign the certificate with specified algorithm (default: 'sha1')

has not been used.

What am i doing wrong or or I have misunderstood the subject ?
I very pleased if some could help on this subject
