CryptoKeyPair
The CryptoKeyPair
dictionary of the Web Crypto API represents a key pair for an asymmetric cryptography algorithm, also known as a public-key algorithm.
A 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.
Instance properties
CryptoKeyPair.privateKey
-
A
CryptoKey
object 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. CryptoKeyPair.publicKey
-
A
CryptoKey
object 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.
Examples
The examples for SubtleCrypto
methods often use CryptoKeyPair
objects. For example:
