php - Can a SHA-1 hash be purely numeric? -

-

Is there any chance that the SHA-1 hash may be completely numeric, or the algorithm ensures that at least Less character of an alphabet?

Edit: I represent it in 16 bases, as is the string given by PHP's sha1 () function.

The constraints of a hex are numbers with a number of 160-bit numbers (10/16) 40 or 6.84227766 × 10 -9
