# Is this exponentation or bitwise XOR

v = g^x

I am unfamiliar with reading cryptography texts. Does this mean gx, or g ⊕ x?

• Exponentiation. ^ meaning XOR is something common in C-like languages, but not in Math AFAIK. – mgibsonbr Jun 20 '13 at 2:00

In SRP, v = g^x means $v = g^x \mod p$, i.e. exponentiation modulo a large prime $p$.
