Introduced WebCrypto API according to W3C spec.
The following methods were implemented:
crypto.getRandomValues()
crypto.subtle.importKey()
format: raw, pkcs8, spki
algorithm: AES-CBC, AES-CTR, AES-GCM,
ECDSA, HKDF, HMAC, PBKDF2,
RSASSA-PKCS1-v1_5, RSA-OAEP, RSA-PSS
crypto.subtle.decrypt()
crypto.subtle.encrypt()
algorithm: AES-CBC, AES-CTR, AES-GCM,
RSA-OAEP
crypto.subtle.deriveBits()
crypto.subtle.deriveKey()
algorithm: HKDF, PBKDF2
crypto.subtle.digest()
algorithm: SHA-1, SHA-256, SHA-384, SHA-512
crypto.subtle.sign()
crypto.subtle.verify()
algorithm: ECDSA, HMAC, RSASSA-PKCS1-v1_5, RSA-PSS
