E integers have the operation cryptoHash/0 which performs a SHA-1 hash on the two's complement representation of the number. This will be an unfortunate permanent choice once SHA-1 is broken.
We should switch to an interface which acknowledges the need for hash algorithm upgrade.

- Simple: rename cryptoHash to sha1Hash. Add other algorithms as desired. --Kevin Reid 17:30, 29 August 2009 (CDT)
- Disadvantage of this: Does not allow code to be sensibly generic over hash algorithms without taking an arbitrary verb to call on Integer. --Kevin Reid 17:30, 29 August 2009 (CDT)
