Hello,

How do I go about getting the SHA1 fingerprint from a PEM certificate I have on disk?

I tried using SecCertificateCreateWithData and getting the SHA1Digest but it dones not match whats in the certificate.

Thanks!

macOS can import PEM certificates directly (using

SecItemImport

). Once you have a certificate object you can get a SHA1 fingerprint by getting the certificate in DER form (

SecCertificateCopyData

) and then doing a SHA1 of that data (with

CC_SHA1

).
