WebIn some cases it can speed up access to individual characters. Imagine string str='ABC' encoded in UTF8 and in ASCII (and assuming that the language/compiler/database knows about encoding).

WebMD5 yields hexadecimal digits (0-15 / 0-F), so they are four bits each. 128 / 4 = 32 characters. SHA-1 yields hexadecimal digits too (0-15 / 0-F), so 160 / 4 = 40 characters. (Since they're mathematical operations, most hashing functions' output is commonly represented as hex digits.)
