| Jul 24, 2019 at 7:50 | comment | added | vdchuyen | Got your point, just because both are too different including keysize and signature algorithm and with your limited resource, you have to figure out your own implement based on existing one. AS MechMK recommend @cryptography is a good place to start. Good luck ! | |
| Jul 24, 2019 at 7:46 | comment | added | Laurent PerrucheJ | Not sure really : we know how to encrypt/decrypt using ECC, our issue is with the CSR format and the specific data to encrypt to generate the signature. I'll try asking on the other side though, thanks. | |
| Jul 24, 2019 at 7:41 | comment | added | user163495 | @LaurentPerrucheJ If you are interested in which cryptographic parameters are used, then perhaps Cryptography is a better place to ask. | |
| Jul 24, 2019 at 7:34 | comment | added | Laurent PerrucheJ | Yes, we know how to do that using openssl. What we can't figure out is the format of the generated CSR, because we generate this without openssl (we're doing this inside a credit card chip, so very limited resources). The signature of the CSR looks very different than an RSA one, and basically we can't figure out what OpenSSL is signing with the key... | |
