I have created public key and private key in my smartcard(Dongle) using safenet sdk's own library. I realized that Both are in PKCS#8 format. Both Private key and Public Key starts with "BEGIN PUBLIC KEY" and "BEGIN PRIVATE KEY" instead of "BEGIN RSA PUBLIC KEY" and "BEGIN RSA PRIVATE KEY".
I also signed CertificationInfo's(ex: Distinguished Names such as common name, postal code etc.). Then I am sending PubLic Key and the signed Data to my swift application to generate csr.
In csr generation step, I converted the public key to rsa format by removing first 32 characters, then convert it to SecKey to generate csr. I found that, after extracting seckey to Data, it is same before and after the SecKey conversion.
But, when i validate the signature with public key, It says that "Signature is invalid". Is it because the public key is in PKCS#1 format and the private key by whom the CertificationInfo is signed is in PKCS#8 format?
If this is the reason, what will be the probable fix to resolve the issue? Do i need to convert the Key format in native end(using C code)? What is the mechanism of generating PKCS#1 format key in C? Or, Is there any way to generate PKCS#8 SecKey using swift?
