Hello,

Yes, PEM_read_RSAPublicKey require PKCS#1 but if public key was
generated with command like:
$ openssl genrsa -out rsa.pem 1024 (PKCS#1 format)
$ openssl rsa -in rsa.pem -out rsapub.pem -pubout
this public key (rsapub.pem) is encoded in SubjectPublicKeyInfo format.
For reading this format you may use PEM_read_RSA_PUBKEY
witch should read this public key.
You may check difference with encoded format executimg commands like:
$ openssl asn1parse -in rsa.pem
$ openssl asn1parse -in rsapub.pem
