    Class DiskCertificateKeyPairProvider

    constructor
    certificateFile privateKeyFile
    dispose getCertificate getCertificateChain getPrivateKey invalidate toJSON

    • Parameters

      • certificateFile: string

        path to the certificate (chain) PEM file

      • privateKeyFile: string

        path to the private key PEM file

      • Optionalpassphrase: string | Buffer<ArrayBufferLike>

        optional passphrase to decrypt privateKeyFile if it is an encrypted PKCS#8 key. Omit for a plaintext key. If the key is encrypted and no (or the wrong) passphrase is given, getPrivateKey() throws PrivateKeyPassphraseRequiredError (fails closed).

      Returns DiskCertificateKeyPairProvider

    • Clears cached secrets so the GC can reclaim sensitive material. After calling dispose the holder will re-read from disk on next access.

      Returns void

    • Alias for dispose. Implements ICertificateChainProvider.invalidate().

      Returns void

    • Returns Record<string, string>
