Applications should not call PEM_ASN1_read(). If you want to read a
private key use PEM_read_PrivateKey() instead.
If you don't supply a callback then it will use the default one which is
console based. This might have failed in previous versions because
you didn't load the algorithms with OpenSSL_add_all_algorithms() (or
equivalent) first.
If you really want it to fail on encryped keys then supply a callback
that returns zero: a return value <=0 is taken as meaning there was a
problem getting the pass phrase.
