CryptoKeyPair dictionary of the Web Crypto API represents a key pair for an asymmetric cryptography algorithm, also known as a public-key algorithm.
CryptoKeyPair object can be obtained using
SubtleCrypto.generateKey(), when the selected algorithm is one of the asymmetric algorithms: RSASSA-PKCS1-v1_5, RSA-PSS, RSA-OAEP, ECDSA, or ECDH.
It contains two properties, which are both
CryptoKey objects: a
privateKey property containing the private key and a
publicKey property containing the public key.
CryptoKeyobject representing the private key. For encryption and decryption algorithms, this key is used to decrypt. For signing and verification algorithms it is used to sign.
CryptoKeyobject representing the public key. For encryption and decryption algorithms, this key is used to encrypt. For signing and verification algorithms it is used to verify signatures.
The examples for
SubtleCrypto methods often use
