The tor_memcmp code is by Robert Ransom, and the tor_memeq code is by me. Both incorporate some ideas from DJB's stuff.

o Security fixes

- Replace all potentially sensitive memory comparison operations
|
|
with versions whose runtime does not depend on the data being
|
|
compared. This will help resist a class of attacks where an
|
|
adversary can use variations in timing information to learn
|
|
sensitive data. Fix for one case of bug 3122. (Safe memcmp
|
|
implementation by Robert Ransom based partially on code by DJB.)
