StringEncrypt — String & File Encryption for JavaScript Developers

StringEncrypt allows you to encrypt strings and files using a randomly generated algorithm, generating a unique decryption code (so-called polymorphic code) each time in the selected programming language.

Available editions

StringEncrypt can be used:

Directly on its website - https://www.stringencrypt.com/
You can download standalone Windows client - https://www.stringencrypt.com/download/
You can use it via WebAPI interface https://www.stringencrypt.com/api/
Visual Studio Code extension - https://marketplace.visualstudio.com/items?itemName=PELock.stringencrypt

The problem with plain text strings

I'm a developer, and I love programming. I'm also an avid reverse engineer. I perform a wide array of software analysis in my daily work and sometimes I find things in compiled applications that shouldn't be exposed to the first person with a simple hex-editor in hand.

What can be found in application binaries?

Everything! I've listed a few examples of the things I found below. Sometimes these things shouldn't even be included in applications at all (they are there due to poor design choices or rushed work), but some are just cannot be avoided.

API keys
Database passwords
FTP passwords
Login credentials
Encryption & decryption keys
Custom code scripts in readable text
Complex SQL queries in plain text
Hidden website endpoints
BitCoin wallets locations
...and many more

Ask yourself, did you ever put some sensitive content in your software that you later regret?

Why should I care?

If any of these things were to fall into the wrong hands, they could be used to compromise your software or your infrastructure.

You don't want this to happen to your software.

Take for example database passwords. A competitor could use them to view your database structure or dump all of its contents. You don't want to lose all your hard work because someone with a simple hex-editor can discover your password in plain text.

The solution — String Encrypt

I've decided to create a simple service called String Encrypt for developers, offering fast string & file encryption without the need to write custom encryption tools over and over again because I did that many times.

String Encrypt can help you hide the things that shouldn't be visible at first glance to anyone with a hex-editor.

StringEncrypt main window

Say hello to polymorphic encryption!

Forget about simple xor encryption! StringEncrypt comes with a unique encryption engine.

It's a polymorphic encryption engine, similar to the encryption methods used by the software protection solutions and advanced computer viruses.

How it works?

Let me explain how the polymorphic encryption process works.

A random set of encryption commands is selected (xor, addition, subtraction, bit rotations, bit shifts, logical negation etc.).
A random set of helper encryption keys is generated.
Every byte of the input string is encrypted with every encryption command in the random set.
Nested encryption loops are constructed
The decryption code in the selected programming language is generated with a reverse set of encryption commands.

You can learn more about polymorphic engines from my articles and projects:

How to build a polymorphic engine in C++ - https://www.pelock.com/articles/polymorphic-encryption-algorithms
Polymorphic engine in 32-bit MASM assembler - https://github.com/PELock/Simple-Polymorphic-Engine-SPE32
Poly Polymorphic Engine - https://www.pelock.com/products/poly-polymorphic-engine

What does it mean?

The encrypted content is different every time you apply StringEncrypt encryption to it.

The algorithm is always unique, the encryption keys are always randomly selected and the decryption code is also unique for every time you use our encryption.

StringEncrypt features

Out of box support for UNICODE (WideChar type in C/C++ languages), UTF-8 (multibyte) & ANSI (single byte) strings encodings
Configurable minimum & maximum number of encryption commands
Different ways to store the encrypted string (as a global or local variable if the selected programming language supports it)
Wide array of supported programming languages
You can automate the encryption process in your builds using our WebAPI interface (JavaScript, PHP, and Python bindings)

How to use StringEncrypt from Node.js code?

The preferred way to install the StringEncrypt module is via npm.

Run:

npm install stringencrypt

The package is published at https://www.npmjs.com/package/stringencrypt

Error codes:

ERROR_EMPTY_STRING (3) - input string is empty
ERROR_EMPTY_BYTES (4) - input file bytes array is empty

ERROR_LENGTH_STRING (6) - string length is too long
ERROR_INVALID_LANG (7) - programming language not supported
ERROR_INVALID_LOCALE (8) - language locale is not supported
ERROR_CMD_MIN (9) - invalid number of minimum encryption commands
ERROR_CMD_MAX (10) - invalid number of maximum encryption commands
ERROR_LENGTH_BYTES (11) - bytes/file length is too long
ERROR_DEMO (100) - you need a valid code to use full version features
