Also of note is that NIST recommends ephemeral Diffie-Hellman - not RSA - for key exchange
For the exact same reason this post is written, because RSA keys do not scale linearly and become "expensive".
I honestly couldn't get through the rest of the article, if you don't think securing information is a high priority, then you probably work for gawker.
- slavak 16y agoCould you explain what causes RSA keys to "not scale linearly"? I don't seem to recall any part of the protocol being non-linear in the key length.
- dekz 16y agoIt was more in terms of comparison with security strength vs key length. For example, 3072 bit RSA keys are equivalent in security strength to 128-bit symmetric keys. To reach 256-bit security strength equivalence, you need 15360-bit RSA keys.
