@bmm6o already answered your main question.
To answer your PPS: the data shown on that webpage is not a hash of any kind. It is an encoding of a structure, using a method called PEM, originally developed for a complete Privacy Enhanced Mail scheme which fell by the wayside, but the PEM encoding is still used a good deal in cryptography. In general that consists of "BEGIN" and "END" lines surrounding base64-encoded data, which is usually an ASN.1 DER structure. For a public key, the DER structure is the SubjectPublicKeyInfo field defined by X.509, the most widely used standard for digital certificates. For example the initial (apparently default) value I see on the webpage
-----BEGIN PUBLIC KEY-----
-----END PUBLIC KEY-----
decodes as a structure containing the following RSA public key (displayed by OpenSSL in hex)
Exponent: 65537 (0x10001)
which as you see does contain a (large) modulus and a (small, conventional) public exponent.
