The password tool creates new, 256-bit AES-encrypted password strings for use with iMacros. Just enter your master password, the password to encrypt and press the "Encrypt" button.
This password tools works with all new iMacros versions: iMacros for Chrome and Firefox V10 and later and the iMacros Browser / iMacros for IE V11.1 and later.
The password de- and encryption is done locally on your computer. No data is sent over Internet.
As a test, you will see that this page even works when your PC is offline. All iMacros versions use 256-bit AES encryption, so the password strings you create can be used with all iMacros versions.
You can download and inspect the encryption scripts enc.js and rijndael.js (from Fritz Schneider's Crypto Utilities).
