[Cryptography-dev] Compute issuerKeyHash

[pepone.onrez]

Hi,

Is there a way to compute the issuer key hash from the certificate issuer?

I tried with:

public_key = issuer_cert.public_key().public_bytes(
    Encoding.PEM,
    PublicFormat.SubjectPublicKeyInfo)
print(hashlib.sha1(public_key).digest())

This doesn't seem to be it, I was previously using oscrypto

issuerSha1 = cert.asn1.public_key.sha1

is there a way to get this info with pyca/cryptography?

Cheers,
Jose
