Package org.bouncycastle.openpgp.operator.jcajce

## Class JcaPGPDigestCalculatorProviderBuilder

- java.lang.Object
- - org.bouncycastle.openpgp.operator.jcajce.JcaPGPDigestCalculatorProviderBuilder

-     public class JcaPGPDigestCalculatorProviderBuilder
      extends java.lang.Object

  A builder for `PGPDigestCalculatorProvider` instances that obtain cryptographic primitives using the JCA API.

  By default digest calculator providers obtained from this builder will use the default JCA algorithm lookup mechanisms (i.e. specifying no provider), but a specific provider can be specified prior to building.

  - ### Method Detail

    - #### setProvider

          public JcaPGPDigestCalculatorProviderBuilder setProvider​(java.security.Provider provider)

      Sets the provider to use to obtain cryptographic primitives.
      Parameters:
        `provider` - the JCA provider to use.
      Returns:
        the current builder.

    - #### setProvider

          public JcaPGPDigestCalculatorProviderBuilder setProvider​(java.lang.String providerName)

      Sets the provider to use to obtain cryptographic primitives.
      Parameters:
        `providerName` - the name of the JCA provider to use.
      Returns:
        the current builder.

    - #### build

          public PGPDigestCalculatorProvider build()
                                            throws PGPException

      Constructs a new PGPDigestCalculatorProvider
      Returns:
        a PGPDigestCalculatorProvider that will use the JCA algorithm lookup strategy configured on this builder.
      Throws:
        `PGPException` - if an error occurs constructing the digest calculator provider.
