WebRSA encryption is modular exponentiation of a message with an exponent e and a modulus N which is normally a product of two primes: N = p * q. Together the exponent and modulus form an RSA "public key" (N, e). The most common value for e is 0x10001 or 65537. "Encrypt" the number 12 using the exponent e = 65537 and the primes p = 17 and q = 23.
