Hi all, So many smart people are in the discussion about MD5 ... I have a temptation to ask: why hash in the first place?!? (does not matter MD5 or SHA-2)
The topic as of late is tied to IOS storing MD5 checksums of authorized SSH public keys for authentication. I presume the sole purpose of this was to simply avoid storing the entirety of the public key (usually ~535 bytes for a 4096-bit key).
