I only know some basics about SSL, symmetric keys and asymmetric keys, and I'd greatly appreciate anyone who can shed some light on this question! My understanding (and feel free to correct anything below here!) is that SSL transactions between a web browser and a web server involve first a ha

Please note that the importance of RSA is going to decline in favor of Elliptic Curve Crypto over GF(p). In particular, by 2010 ECC will be mandated. I suspect there are cryptographic reasons for it. __ OpenSSL Project

Hi all, This is a general crypto question and I hope someone could help me out. Often we use RSA of 512, 1024, 2048, 4096, etc. bit lengths. Are other sizes such as 520/1045 bit "valid"? Mathematically, it should work, but are there reasons why odd sizes are not to be used? _
