now it worked with "sha1" but question whysha256 did not work because when I check the cert Details and "signature hash algorithm" is sha256 so I assumed that the value should sha256.

my requirement is to get thumbprint of the certificate and I am trying to use this $thumb = openssl_x509_fingerprint($certContent,"RSA-SHA256",false); $thumb1 = openssl_x509_fingerprint($certContent,"sha256",false); But the return of the above is not matching with the thumbprint. when I open the cert and check "Details" --> Thumbprint , it is different than what is returned from above function. when I check here "signature algorithm = sha256RSA" and "signature hash algorithm = sha256" Please let me know if I am missing something.
