Where is an official documentation for ASN1 structure and values of x509 certs?
Using OpenSSL command like
openssl asn1parse -in server.der -inform DER I can see how the cert is structured, but, for example, value
OBJECT :sha256WithRSAEncryption is HEX
2A 86 48 86 F7 0D 01 01 0B, or countryName identifier is
55 04 06 - where are all this values documented?
