Is calculating an MD5 hash less CPU intensive than SHA family functions?
...ider that a recent hard disk will run at about 100 MB/s, and anything over USB will top below 60 MB/s. Even though SHA-256 appears "slow" here, it is fast enough for most purposes.
Note that OpenSSL includes a 32-bit implementation of SHA-512 which is quite faster than my code (but not as fast as t...

... types of hardware. Serial ports aren't as common as they used to be, but USB chips which emulate serial ports are pretty popular in the design of specialized hardware. Characters from such things are handled at the application level, since the OS will have no way of knowing that a sequence of inp...

The BIOS provides a single central device/feature selection su...
