If that's the concern, then I'm glad to say that I have very reassuring
news for you. No attacks are known on /dev/urandom, not even theoretical
ones.

(And no attack is known on SHA-1, not even a theoretical one.)

(Don't confuse a remote risk that someone might discover a theoretical
attack on SHA-1 with knowledge that we already know of a theoretical
attack on SHA-1.)
