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.

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.

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 (PHP and Python bindings)

How to use StringEncrypt from PHP code?

The preferred way of StringEncrypt module installation is via composer(https://getcomposer.org/).

Run:

composer require pelock/stringencrypt

The installation package is available at https://packagist.org/packages/pelock/stringencrypt

Basic string encryption usage example (with default options)

$result = $stringEncrypt->encryptString('Hello!', '$label');

if ($result === false) {

if (($result['error'] ?? null) !== ErrorCode::SUCCESS) {
    echo 'API error: ' . (string) ($result['error'] ?? 'unknown') . "\n";
    exit(1);
}

echo (string) $result['source'] . "\n";

Return values:

$result["error"] (int) - error code
$result["source"] (string) - decryptor source code
$result["expired"] (boolean) - expiration flag
$result["credits_left"] (int) - number of credits left
$result["credits_total"] (int) - initial number of credits

Error codes:

ERROR_SUCCESS (0) - everything went fine
ERROR_EMPTY_LABEL (1) - label parameter is empty
ERROR_LENGTH_LABEL (2) - label length is too long
ERROR_EMPTY_STRING (3) - input string is empty
ERROR_EMPTY_BYTES (4) - input file bytes array is empty
ERROR_EMPTY_INPUT (5) - input source (either string or file) is missing
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

Free demo version limitations

The free demo version comes with some limitations.

Feature	Demo version	Full version
String encryption	✅	✅
File encryption (text or binary file)	❌	✅
Nested polymorphic loops	❌	✅
Max. label length (characters)	`10`	`64`
Max. string length (characters)	`10`	`4096`
Max. file length (bytes)	—	`4 MB`
Min. number of encryption commands	`3`	`50`
Max. number of encryption commands	`3`	`50`

Pricing

To remove the limitations and support our project and its development, you need to buy an activation code at:

https://www.stringencrypt.com/buy/

Each activation code has an assigned number of usage credits. You can use the software in full version as many times as you have usage credits on your account balance.

How to get a free activation code?

You can get a free activation code (500 usage credits) if you can advertise StringEncrypt service with a link to the project site https://www.stringencrypt.com/ at:

Programming sites & forums
Programming blogs
Technical articles
X or any other social media site
...or any other website related to programming and development

Send me all the details at my contact address and if it's legit - bam!, you got yourself a free code :)

Changelog

2026-04-14

Encryption engine updated to v1.5.0 with major algorithmic improvements.

Support for new programming languages added:

Kotlin
Dart
Go
Rust
Swift
Lua
PHP
Objective-C
NASM

Nested polymorphic encryption loops (matryoshka-style)

Available only for paying customers. The decryption loop can now contain randomly generated inner loops (up to 3 levels deep), each with 1–3 encryption commands. This dramatically increases the complexity of the generated polymorphic code, making static analysis significantly harder. Supported in all languages except Haskell. Assembly languages (MASM/FASM/NASM) use push/pop with randomly generated named labels for inner loop nesting.

Related to the nested loops, the C/C++ loop constructs are now using volatile keyword to prevent compiler loop unrolling, and it makes advanced string extraction tools unusable.

Bugfixes

Fixed Python formatting to be compatible with PEP rules.
Fixed Ruby generator by using valid method of storing encrypted unicode characters array.
Fixed AutoIt generator.

6 new encryption VM instructions:

neg — two's complement negation (self-inverse)
swap — nibble swap for 8-bit / byte swap for 16-bit values (self-inverse)
c_rol / c_ror — counter-dependent bit rotation, shift amount varies per character making frequency analysis nearly impossible
xor_shr / xor_shl — hash-like self-XOR mixing functions inspired by algorithms such as MurmurHash and SplitMix (self-inverse)

The total number of encryption VM instructions is now 17 (up from 11), providing a vastly larger space of possible encryption combinations.

New syntax highlighting

Legacy Syntax Highlighter library was replaced with modern Prism highlighter.

SDKs

Official StringEncrypt PHP package published on Packagist
StringEncrypt Python package on PyPi upgraded

I hope you like it and you will try it at least :)
