Sample run with Firefox on Mac OSX

RSA 1,024   161 ms
RSA 2,048   924 ms
ECC 128-bit  34 ms
ECC 160-bit  43 ms
ECC 256-bit  27 ms

What can you observe about the performance of the key pair generation?

RSA increases greatly with an increasing key size, but ECC is fairly constant.

For HMAC:

napieraccount@ubuntu:~$ cat 1.js
var crypto = require('crypto');

var key = 'qwerty';
var message = 'Hello';
var hash = crypto.createHmac('md5', key).update(message);

console.log(hash.digest('hex'));
console.log(hash.digest('base64'));

Salted__$<1F>gc<67>SA<53><06>]<5D>h]5ë<35>;<3B><><EFBFBD><EFBFBD>

We can see the word "Salted__".

When we convert we get:

(53 61 6C 74 65 64 5F 5F 24)  (1F A8 67 63 B8 53 41 90) (06C55D9F685D35C3ABA13BE5FAFBD4)

The format is (signature "Salted__"), (Salt), and (Cipher).

For encryption/decryption:

napieraccount@ubuntu:~$ cat enc.txt 
U2FsdGVkX18kH6hnY7hTQZAGxV2faF01w6uhO+X6+9Q=
napieraccount@ubuntu:~$ openssl enc -aes-256-cbc  -pass pass:"qwerty" -d -base64 -S 241fa86763b85341 -in enc.txt -out out.txt
napieraccount@ubuntu:~$ cat out.txt
