Functions

source

(format: KeyFormat, key: RsaPssPubCryptoKey | RsaPssPrivCryptoKey): Promise<ArrayBuffer | JsonWebKey>

Export an RSA_PSS public or private key

example
const pubKeyJwk = await RSA_PSS.importKey("jwk", keyPair.publicKey.self);
example
const pubKeyJwk = await keyPair.publicKey.importKey("jwk");
source

(algorithm?: Omit<EnforcedRsaHashedKeyGenParams, "name">, extractable?: boolean, keyUsages?: KeyUsage[]): Promise<RsaPssProxiedCryptoKeyPair>

Generate a new RSA_PSS keypair

example
const keyPair = await RSA_PSS.generateKey();
source

(algorithm?: Omit<EnforcedRsaHashedKeyGenParams, "name">, extractable?: boolean, keyUsages?: KeyUsage[]): Promise<RsaPssProxiedCryptoKeyPair>

Generate a new RSA_PSS keypair

alias

generateKey

example
const keyPair = await RSA_PSS.generateKeyPair();
source

(format: KeyFormat, key: BufferSource | JsonWebKey, algorithm: Omit<EnforcedRsaHashedImportParams, "name">, extractable?: boolean, keyUsages?: KeyUsage[]): Promise<RsaPssProxiedPubCryptoKey | RsaPssProxiedPrivCryptoKey>

Import an RSA_PSS public or private key

example
const key = await RSA_PSS.importKey("jwk", pubKey, { hash: "SHA-512" }, true, ['verify']);
source

(saltLength: number, key: RsaPssPrivCryptoKey, data: BufferSource): Promise<ArrayBuffer>

Sign a given payload

example
const message = new TextEncoder().encode("a message");
const signature = await RSA_PSS.sign(128, keyPair.privateKey.self, message);
example
const message = new TextEncoder().encode("a message");
const signature = await keyPair.privateKey.sign(128, message);
source

(saltLength: number, key: RsaPssPubCryptoKey, signature: BufferSource, data: BufferSource): Promise<boolean>

Verify a given signature

example
const message = new TextEncoder().encode("a message");
const isVerified = await ECDSA.verify(128, keyPair.publicKey.self, signature, message);
example
const message = new TextEncoder().encode("a message");
const isVerified = await keyPair.publicKey.verify(128, signature, message);
