Maybe it's a simple question, but i want to know if there is any problem that i have a request using a ECDSA key with SHA-256 and i want to issue a certificate where the CA uses RSA with SHA 1.
In some tests, a ECDSA with sha1 and a CA with RSA with sha1 it was sucess. But with ECDSA sha256 it gives the error: Signature verification error 2857:error:0D0C50A1:asn1 encoding routines:ASN1_item_verify:unknown message digest algorithm:a_verify.c:141: I'm using a P-192 ecdsa key. Another question is: Is there any problem to use a different kind of key on the request that the Certificate Authority has? Thanks, -- Rick Lopes de Souza
