Experience the next generation of data security with Ladhe’s Encryption Utility (LE)—a cutting-edge, post- quantum-safe encryption tool designed for Mac Terminal. Built with advanced features and unparalleled encryption power, LE ensures your sensitive data remains protected from modern and future threats.
Now that LE is cross-platform, you can encrypt and decrypt files seamlessly on both macOS and Windows.
Open door hacking challenge! LE secures your data, information, and files on your PC or server—even if hackers try to attack through the front door. Unlike traditional encryption, LE is built to withstand the rising threats of AI-powered attacks and future quantum computing capabilities.
With LE, you’re not just protecting files—you’re helping to eradicate hacking and safeguard the digital world for the years to come.
Given Ladhe's Encryption, orgs/users and developers gain unmatched security.
When access requires a PasswordKey, is within a specified time range, and is restricted to a defined geo-locationKey,
Then only authorized users, at the right time and place, with correct pin and MFA/static OTP (non expiring) can unlock the data!

- Clone the repository or download the zip:
git clone https://github.com/SPAlgorithm/LE.gitOr download the zip and extract it.
-
Install LE:
-
For Mac
-
Tap on LE.dmg and copy/move LE and LE-AIGPT to a local folder.
-
Double click on LELocation shortcut to enable permissions.
-
For Windows
-
Tap on LE Windows and extract LE to a local folder.
-
-
Setup LE:
On Mac, add current folder to the Path, so that you can execute le instead of ./LE
PATH="$PATH:."LE --setupOr:
LE -sIf you run setup, then you are agreeing to all the terms and conditions! LE uses location and messages services, please enable these if you are using Geo Location and MFA capabilities.
This will create a cer.le certificate. This will also create .leignore file in current folder. You may be prompted to enter password of your machine in key chain.
If you want to buy licenced copy,please share cer.le with us. Contact spalgorithm@gmail.com.
- Encrypt a test file:
echo Testing > example.txtLE -e example.txt -jYou should see example.letxt in the folder.
Encrypt a plain text:
LE -e "Testing" --PlainTextEncrypt a plain text with Pin::
LE -e "Testing" -1 1122 --PlainTextDecrypt a plain text Cipher:
LE -d LeCipher --PlainTextLE -d LeCipher -1 1122 --PlainText🔑 Password Lock Security, Pin Security, MFA Security,Time-Lock Security , Geo Location Security

To get OTP to your configured phone:
LE -4 example.letxt -1 1234 Use that OTP to decrypt :
LE -d example.letxt -w pass.letxt -j -1 1234 -3 "123456"- Create a PasswordKey file:
echo TestingPassword > pass.txtThis PasswordKey file now contains the password "TestingPassword".
- Encrypt the PasswordKey file:
The PasswordKey file needs to be encrypted/decrypted with 4 digit pin or MFA enabled.
LE -e pass.txt -q -j -1 1234The PasswordKey file (pass.letxt) is now encrypted with pin 1234 and can be used for encrypting files or folders.
LE -e pass.txt -q -j -1 1234 -2 "+1XXXXXXXXX,+1YYYYYYYYYY"- Create a location key file:
Location files needs to be encrypted/decrypted with 4 digit pin.
LE -x "1 Infinite Loop. Cupertino, CA 95014 United States" -m 100 >> location.csvLE -x "1560 Broadway, Manhattan, NY 10036 usa" -m 500 >> location.csvLocation.csv will contain 2 Geo Location points now if valid addresses are provided.
- Encrypt the location key file:
LE -e location.csv -v -1 1234 -g -m 200 -jLE -i location.lecsv Note: Please backup your .leignore file, repair will recreate .leignore file.
This will recreate a cer.le certificate and clean up some of the current location information.You may be prompted
to enter password of your machine in key chain.
Ladhe's Encryption can play a crucial role in mitigating the Harvest Now, Decrypt Later (HNDL) threat, which is a major concern in the era of quantum computing.
How Ladhe’s Encryption Solves HNDL
1.Quantum-Safe from Day Zero
Unlike classical RSA and ECC, which are vulnerable to Shor’s algorithm, Ladhe's Encryption is designed to be resistant to quantum attacks, making it an ideal defense against adversaries who collect encrypted data today with the hope of decrypting it in the future.
2.Unmatched Key Strength
Even Version 1.0 of Ladhe’s Encryption (with just a 9-byte public key) is trillions of times stronger than 4096-bit RSA.This immense cryptographic strength ensures that data remains secure even against future advancements in computing power.
3.Dual Algorithm (Symmetric & Asymmetric Support)
Supporting both symmetric and asymmetric encryption allows for dynamic adaptation, ensuring that even legacy systems can transition to post-quantum security without sacrificing performance or compatibility.
4.Crypto Agility
Ladhe’s Encryption is designed for crypto agility, meaning it can be integrated into existing cryptographic infrastructures and updated as new threats emerge, preventing long-term vulnerabilities. Resistant to Future Quantum Breakthroughs
Since it is not based on factorization, discrete logarithms, or elliptic curve cryptography, Ladhe’s Encryption does not suffer from the weaknesses that quantum computers exploit.
Why Does This Matters?
Governments, enterprises, and individuals storing sensitive information today are at risk because encrypted data stolen now can be decrypted later when quantum computers reach maturity. By adopting Ladhe’s Encryption now, organizations can protect their critical data before it’s too late.
Challenge to break LE:
While Ladhe’s Encryption may be at stage ZERO, but we boldly challenge QUANTUM computers, AI, ChatGPT, and the world's smartest minds to break it! Our goal is to keep world safer!
Enjoy LE!
