   Why is bcpowmod useful?

   • It is useful to have bcpowmod available because it is commonly used to implement the RSA algorithm. The function bcpowmod (v, e, m) is supposedly equivalent to bcmod (bcpow (v, e), m). However, for the large numbers used as keys in the RSA algorithm, the bcpow function generates a number so big as to overflow it.

   What is bcpow V E M?

   • The function bcpowmod (v, e, m) is supposedly equivalent to bcmod (bcpow (v, e), m). However, for the large numbers used as keys in the RSA algorithm, the bcpow function generates a number so big as to overflow it. For any exponent greater than a few tens of thousands, bcpow overflows and returns 1.

   Does PHP have bcpowmod?

   • Versions of PHP prior to 5 do not have bcpowmod in their repertoire. This routine simulates this function using bcdiv, bcmod and bcmul. It is useful to have bcpowmod available because it is commonly used to implement the RSA algorithm. The function bcpowmod (v, e, m) is supposedly equivalent to bcmod (bcpow (v, e), m).
