Why Notelock?
In today’s digital era, standard text editors store your notes in unencrypted plain text files (.txt). If your device is shared, lost, stolen, or accessed without authorization, your sensitive data—such as passwords, financial records, personal journals, recovery keys, and trade secrets—is instantly exposed.
Notelock solves this problem once and for all.
Save as Standard Plain Text (.txt)
For quick, non-sensitive notes, scripts, and general documentation. Operates seamlessly with standard text tools and full Windows Notepad interoperability.
Save as Encrypted Documents (.dhin)
For private files that require password protection. Your content is encrypted using military-grade AES-256 before it ever touches your hard drive.
Military-Grade AES-256 Encryption (.dhin)
Notelock utilizes Advanced Encryption Standard (AES) with 256-bit key length—the exact cryptographic standard adopted by governments, financial institutions, and military organizations worldwide.
Zero-Knowledge Architecture
Notelock never stores your passwords or encryption keys on your hard drive, in memory after closure, or on external servers.
Local Cryptographic Processing
All encryption and decryption operations take place locally on your PC. No data ever leaves your computer.
Master Password Protection
When you encrypt a document into the custom .dhin format, only someone who possesses your exact master password can decrypt and read the file.
Brute-Force Resistance
Without the master password, an encrypted .dhin file appears as scrambled cipher data that is virtually uncrackable.
