Cryptographic Hashing, Salt & Security Standards Guide
What is the difference between Cryptographic Hashing and Encryption?
Hashing is a strictly one-way mathematical function that transforms arbitrary-length input data into a fixed-length string of bytes (the digest). It is mathematically designed to be irreversible — you cannot "decrypt" a hash back to its original plaintext. In contrast, Encryption (such as AES-256 or RSA) is a two-way function intended to conceal data, requiring a private key or password to decrypt the ciphertext back into plaintext.
Why are MD5 and SHA-1 deprecated for passwords and digital signatures?
Both MD5 (128-bit) and SHA-1 (160-bit) have known cryptographic collision vulnerabilities, meaning practical attacks exist where attackers can generate two distinct files with identical hash values. While MD5 and SHA-1 remain popular and useful for fast non-cryptographic checksum verification, software caches, and Git commit IDs, all modern web standards, API signing protocols, and security certifications require SHA-256, SHA-512, or SHA-3/Keccak.
How does HMAC and Secret Salt prevent Rainbow Table attacks?
A Keyed-Hash Message Authentication Code (HMAC) combines a cryptographic hash function with a secret key. Without knowledge of the secret key, attackers cannot forge a valid signature or use precomputed rainbow table lookup databases. HMAC ensures both data integrity (the message was not modified in transit) and authenticity (the message originated from a party holding the secret key).
Zero-Server Privacy Guarantee: Is my plain text safe?
Yes, 100% safe. This utility executes exclusively inside your local browser using the hardware-accelerated W3C Web Cryptography API (window.crypto.subtle) and optimized client-side bitwise engines. No plaintexts, secret keys, passwords, or computed digests are ever transmitted over the network or stored on RiazHub servers.
