-## The WebCrypto specification
-
-The WebCrypto specification is for performing basic cryptographic operations in
-web applications, such as hashing, signature generation and verification, and
-encryption and decryption. The API is also for applications to generate and/or
-manage the keying material necessary to perform these operations. Uses for this
-API range from user or service authentication, document or code signing, and the confidentiality and integrity of communications.
-
-The latest version of the specification can be found at: http://www.w3.org/TR/WebCryptoAPI/
