I am writing a program doing ECDH with a C client, which uses WolfSSL.
What did you see happen?
Key exchange procedure failed at:
pub, err := x509.ParsePKIXPublicKey(data)
Error message is:
asn1: structure error: tags don't match (16 vs {class:3 tag:2097151 length:0 isCompound:true}) {optional:false explicit:false application:false private:false defaultValue: tag: stringType:0 timeType:0 set:false omitEmpty:false} publicKeyInfo @5
What did you expect to see?
The key should be OK, because OpenSSL said so:
$ openssl ec -in pubkey.der -inform DER -pubin -text -noout
read EC key
Public-Key: (256 bit)
