Chris:
... and, furthermore, the PRNG should be seeded with some truly random inputs, or as random as can be available. RFC 1750 [1750] contains more discussion on this and suggestions for randomness. Implementors should note well the importance of truly random values where needed in this document. They should also heed the well-meant, anecdotal warning that implementing PRNG functions are difficult to get right.
I think that the term "truly random" ought to be avoided. In the subsequent paragraph. the term "entropy" is used. I think that is a better way to go. I propose:
... and, furthermore, entropy needs to be added to the PRNG. RFC 1750 [1750] offers suggestions for sources of entropy. Implementors should note the importance of entropy and the well-meant, anecdotal warning about the difficulty in properly implementing PRNG functions. Russ
