AsymmetricKeyBuilder

​

Methods

​

buildGenerated()

buildGenerated(): Promise<PrivateKey>

Build a new private key based on the configured properties.

​

Throws

• InvalidArgumentError If the chosen key size or the key itself is invalid.

​

Returns

Promise<PrivateKey> Promise<PrivateKey> A promise that resolves to the generated private key.

---

​

buildPrivateFromDer()

buildPrivateFromDer(der: ArrayBuffer): Promise<PrivateKey>

Import a private key from a DER-encoded blob. The imported key will inherit the properties (algorithm, purposes, exportability) set on this builder.

​

Parameters

der

ArrayBuffer The DER-encoded private key in PKCS#8 format.

​

Throws

• InvalidArgumentError If the provided key is invalid.

​

Returns

Promise<PrivateKey> Promise<PrivateKey> A promise that resolves to the imported private key.

---

​

buildPublicFromDer()

buildPublicFromDer(der: ArrayBuffer): Promise<PublicKey>

Import a public key from a DER-encoded blob. The imported key will inherit the properties (algorithm, purposes) set on this builder.

​

Parameters

der

ArrayBuffer The DER-encoded public key in SubjectPublicKeyInfo format.

​

Throws

• InvalidArgumentError If the provided key is invalid.

​

Returns

Promise<PublicKey> Promise<PublicKey> A promise that resolves to the imported public key.
