crand

README

Crand

A library that proxies crypto/rand with diverse simple functions.

Values returned exclude the maximum.

Godoc

Example

Generate a secure, random token

fmt.Printf("Token: %v", crand.String(20))

Disclaimer

I have no formal education in cryptography. The randomness is derived from crypto/rand and I've implemented safeguards against modulus bias.
