openssl_x509_fingerprint() and context option

###SSL context option

  • peer_fingerprint: string|array

Aborts when the certificate fingerprint doesn't match the given hash. The behaviour depends on the variable type:

  • when a string is passed, depending on the length MD5 (32) or SHA1 (40) will be used as the hashing algorithm.
  • when an array is passed, the key determines the algorithm (e.g. "sha256") and the corresponding value is used to compare against.

For example:
