[crypto] RSA-576 factored

[R. Hirschfeld]

For those who haven't heard yet, RSA-576 was factored last week:

RSA-576
=
188198812920607963838697239461650439807163563379417382700763356422988859715234665485319060606504743045317388011303396716199692321205734031879550656996221305168759307650257059

I expect this result will be discussed at the Cryptography Working
Group's Workshop on Factoring Large Numbers in Utrecht this Friday.
Herman, can you provide more details?
