RSA Asymmetric Suite

Generate 2048/4096-bit key pairs, export PEM files, encrypt with public keys, decrypt with private keys.

Open tool →

Image Steganography

Hide secret messages inside images using LSB pixel manipulation. Completely undetectable to the human eye.

Open tool →

Ciphers & Encryption

AES-256 symmetric encryption, Caesar shift cipher, and Vigenère polyalphabetic cipher — all client-side.

Open tool →

Cryptographic Hashing

MD5, SHA-1, SHA-256, SHA-512 digests for text input or local file checksum verification via drag-and-drop.

Open tool →

Password Analyser

Entropy calculation, brute-force time estimation, requirements checklist, and a secure random password generator.

Open tool →

Multi-Format Converter

Convert between plain text, binary, hexadecimal, Base64, decimal ASCII, and octal representations.

Open tool →

Platform Capabilities

Core Promise
100% Client-Side Processing
Every operation runs in your browser's sandboxed memory. No data is transmitted, stored, or logged on any external server. Your secrets stay yours.

Security Modules
Encryption
RSA + AES
Both asymmetric public-key and symmetric passphrase encryption in one platform.
Steganography
Hide data in plain sight
Embed secret payloads into image pixels using LSB manipulation. The encoded image looks identical to the original — completely invisible to the human eye.
Password Safety
Entropy Analysis
Calculates mathematical entropy bits and estimates real-world GPU crack times.
How SecureTools Works
1
Select a Tool
Choose from 7 specialised security modules — encryption, hashing, encoding, password analysis, steganography, or key generation.
2
Input Your Data
Enter text, upload files, or paste keys. All input stays in your browser's volatile memory — never transmitted externally.
3
Process Locally
Cryptographic operations execute using browser-native APIs (Web Crypto, CryptoJS) at hardware-accelerated speeds.
4
Export Results
Copy outputs to clipboard, download PEM keys, or save encoded images. Your session log tracks all operations locally.
