RandomSecure
Our Approach to Privacy
Our cybersecurity suite implements a rigorous, client-side computational methodology that guarantees absolute data sovereignty through localized processing protocols. Your data stays with you.
Computational processes are systematically confined to client-side environments, employing cryptographically secure mechanisms that categorically prevent unauthorized data transmission or persistent storage vectors. Our platform's architectural design incorporates a comprehensive "zero knowledge" paradigm, systematically eliminating external data access vectors and ensuring complete computational isolation.
How Our Tools Work
Random Number Generator
Implementation:
Our random number generator uses the Web Cryptography API's crypto.getRandomValues() method, which provides cryptographically secure random values. This is far superior to the standard Math.random() function for security applications.
Security Measures:
- Uses a cryptographically secure pseudo-random number generator (CSPRNG)
- Generated values can't be predicted or reproduced, even with knowledge of previous values
- No server requests are made during the generation process
Password Generator
Implementation:
Our password generator creates high-entropy passwords using cryptographically secure random values to select characters from specified character sets.
Security Measures:
- Uses the same CSPRNG as our random number generator for character selection
- Ensures that passwords contain at least one character from each selected character set
- Shuffles the final password using a secure algorithm to prevent pattern analysis
- Never stores or transmits generated passwords
Passphrase Generator
Implementation:
Our passphrase generator selects random words from curated word lists to create memorable but secure passphrases.
Security Measures:
- Uses CSPRNG for word selection to ensure unpredictability
- Word lists are contained directly in the JavaScript code, with no external requests
- Optional features like capitalization and number addition increase entropy
- Provides entropy estimation to help understand the security level of your passphrase
Encryption & Decryption Tool
Implementation:
Our encryption tool uses the Advanced Encryption Standard (AES) with a 256-bit key length, implemented via the CryptoJS library.
Security Measures:
- Uses AES-256-CBC, a widely trusted and vetted encryption algorithm
- Employs PBKDF2 (Password-Based Key Derivation Function 2) with 1000 iterations to derive encryption keys from passwords
- Generates a unique random salt (IV) for each encryption operation
- All encryption/decryption operations happen entirely in your browser
- Keys and plaintext are never transmitted over the network

Technical Security Details
Our cryptographic implementations utilize industry-standard algorithms and methods:
AES-256 Encryption
Advanced Encryption Standard (AES) with a 256-bit key length provides military-grade encryption that is computationally infeasible to break using current technology. This symmetric encryption algorithm is used by governments, financial institutions, and security organizations worldwide.
PBKDF2 Key Derivation
Password-Based Key Derivation Function 2 applies a pseudorandom function to the input password along with a salt value and repeats the process many times to produce a derived key. This technique protects against brute force attacks by making each password verification computationally expensive.
Web Cryptography API
This built-in browser API provides standardized access to cryptographically secure random number generation and other cryptographic primitives. Unlike JavaScript's Math.random(), which is not cryptographically secure, the Crypto.getRandomValues() method provides randomness suitable for generating encryption keys and other security-sensitive values.
