Web Crypto API

Checking compatibility...

Perform cryptographic operations in web applications with the Web Crypto API. Learn to encrypt data, generate keys, and verify signatures.

Security Context

Web Crypto API requires a secure context (HTTPS) for most operations. Some methods may be restricted or unavailable in non-secure contexts to prevent potential security vulnerabilities.

Encryption and Decryption

Keep sensitive information private by turning readable data into scrambled code that only authorized users can unlock. This example shows how to protect data with a digital key and later recover the original information.

Hashing

Create unique digital fingerprints for any piece of data. Hashing converts information into fixed-length codes that can verify data integrity - like checking if a downloaded file matches the original or securely storing password information.

Digital Signatures

Prove who created or approved digital content, similar to a handwritten signature but much more secure. Digital signatures let you verify the authenticity of messages and documents while ensuring they haven't been tampered with.
