Encryption and Hashing Utility API
The Encryption and Hashing Utility API is a universal cryptography service designed for developers, security engineers, and software platforms. It supports modern hashing algorithms, secure encryption, and reliable decryption across multiple standards — all accessible via simple GET/POST requests.
Whether you’re building a secure authentication system, data protection layer, or enterprise-grade crypto solution, this API provides everything you need in one place.
The API caters to a wide range of programming languages, including but not limited to: C, Clojure, C#, GO, Java, JavaScript, Kotlin, Node.js, Objective-C, OCaml, PHP, PowerShell, Python, R, RapidQL, Ruby, Shell, and Swift.
Introduction
API Overview
The Encryption & Hashing Utility API acts as an all-in-one crypto toolkit for developers. From hashing passwords with Argon2 or bcrypt to encrypting data with AES, RSA, Blowfish, or ChaCha20, it provides a consistent and reliable interface.
The API is flexible, lightweight, and developer-friendly, making it perfect for secure app development, cloud services, and fintech solutions where cryptography is mission-critical.
Key Features:
✅ Multi-Algorithm Support – SHA-256, SHA-512, MD5, bcrypt, Argon2, Blake2, AES, RSA, Blowfish, ChaCha20
✅ Universal Actions – Hash, Encrypt, or Decrypt data via the same endpoint
✅ Strong Password Hashing – Industry-standard bcrypt
& argon2
support for safe credential storage
✅ Symmetric & Asymmetric Encryption – Secure both fast (AES, ChaCha20) and legacy (RSA, Blowfish) use cases
✅ Developer-Friendly Integration – Works with GET for quick checks or POST for production apps
✅ Security-First Design – Uses Base64 encoding for safe handling of ciphertext, IVs, and nonces
Additional Highlights:
🔹 All-in-One Utility – No need for multiple libraries; everything is available in one API
🔹 Enterprise Ready – Ideal for auth systems, tokenization services, and sensitive data handling
🔹 Legacy + Modern Support – Covers classic algorithms like MD5/Blowfish plus modern standards like Argon2/ChaCha20
🔹 Error-Resilient – Built-in error handling for unsupported algos, missing keys, or decryption failures
🔹 Secure by Default – Encourages strong crypto practices (argon2 for passwords, AES for fast encryption, RSA for key exchange)
🔹 Future-Proof – Designed to add more algorithms and modes as cryptography evolves

Frequently Asked Questions
What is the Encryption & Hashing Utility API used for?
It’s an all-in-one cryptography API that lets you hash, encrypt, and decrypt data using industry-standard algorithms like Argon2, bcrypt, AES, RSA, Blowfish, and ChaCha20.
Which password hashing algorithms are supported?
The API supports bcrypt and Argon2, the strongest password hashing standards used in modern authentication systems.
Can I encrypt and decrypt sensitive data?
Yes. The API supports both symmetric encryption (AES, ChaCha20, Blowfish) and asymmetric encryption (RSA). This makes it ideal for secure data exchange and storage.
Is it safe to use in production?
Absolutely. The API was designed with security-first principles, using Base64-safe encoding for ciphertext and supporting only trusted cryptographic algorithms.
Does the API support legacy algorithms like MD5 or SHA-1?
Yes, but only for compatibility and checksum purposes. For new implementations, we strongly recommend modern algorithms like SHA-256, Argon2, or bcrypt for better security.
