I'm totally lost with is standard RSASSA-PKCS1-v1_5. I have commands that signs document and checks signature below.
openssl dgst -sha256 -sign private-key.pem -out aaa.txt.sha256 aaa.txt
openssl dgst -sha256 -verify public-key.pem -signature aaa.txt.sha256 aaa.txt
Does these sign/verify procedures complains RSASSA-PKCS1-v1_5 standard?
