It is AES 256.

However, this software does not only use AES algorithm.
Before the text is sent to AES encryption, it is first encrypted by CTI2 encryption, which is my own creation of encryption algorithm.

To Encrypt: Text > CTI2 > AES128 + SHA512(Password) > Encrypted Text

To Decrypt: Encrypted Text > AES128 + SHA512(Password) > CTI2 > Original Text

Hi, the key size used by this encryption is 128 (AES 128)

Thanks for the reply.

Also, does it use AES 256?

Introduction to CTI Text Encryption.

CTI Text Encryption is a text encryption tools. It able to encrypt text, articles, messages into random, meaningless code. And then at a later time, it can be decrypted into original message when needed.

A simple example:

Original Text (before encryption):
The quick brown fox jump over the lazy dog.

Encrypted Text (after encryption):
A+y49h+rdJLIoIx7E2lG12MQrNVS4i4BGbe4+ji0NeaEkAexrOgoWa865+GioUeDMDOMZHdxfYP1JU54ogvw/Q==

Decryption Result of the Encrypted Text:
The quick brown fox jump over the lazy dog.

Why do We Need Text Encryption?

Everyday, we sent emails, take notes, delievered private message in forums, sending messages through online chatting system. Some of these messages might contain very important information and privacy.

Is it safe to just send it in plain, pure human understandable text through internet?

A warning of Internet Explorer

Sending pure human understandable text through internet is not safe.

There are many ways to get these text exposure. Text, that send through internet has a very high change to be viewed by 3rd party or unauthorized person.

If you are sending or saving some sensitive/privacy information, it is always recommended to take one more extra step to keep your message safer - Encrypt Your Text.

CTI Text Encryption is designed to this job.

One Way Encryption

Note: This function is available in CTI Text Encryption 3.0

When you create a new password, you might used your birthdate, phone number, your personal identity card number, or simply use keyboard sequence such as QWERTY, 12345 and asdf.

According to many experienced IT security experts and password hacking studies , a recommended strong password should comprise of mixture of

Upper Case Letter
Lower Case Letter
Numbers
and symbols

but, are you going to remember a sentence something like this?

jF2$o*!Jd1x9P@v#qa^9

no.

This software can help you easily generate a complex password in ease. Key in any beloved phrases, and the password code is generated automatically.

Features:

Support Multi-Language Input Text
Friendly user, easy to use, light weight, standalone, portable.
Able to apply custom UI (User Interface) Language, including Right to Left UI.
Encrypt with up to 4 combination of password.

Awards:

Donations will be paid to the developer of this software.
Thanks.

Hi, sorry for the late reply.

Current password length limit is 32767 characters, including white space.

Each of the textbox of password can be filled by 32767 characters.

I like the app. It's the best open source implementation of the idea I've seen yet, and I've tested 3 or 4. Question though, are you using AES 256 for the encryption? Also, what is the limit on password length?

There were a few apps that worked great but had 8 character limits, which is no good for more secure needs.

Thanks for the reply!

It would be awesome if you implement a Drag and Drop option of a text file onto the program icon.......

adriancs — Sun, 20 Jan 2013 00:47:46 GMT

I see. Good suggestion thought.

will try to implement it.

You're welcome.

However I actually meant dragging a text file into the text area and then drop it.

Hi Adrianics,

Thank you for your excellent app.

My question is whether it is possible to create a drag and drop feature?

That would really increase the value of this program in my opinion.

Kind regards,

Rob
