Class PBEParameterSpec

java.lang.Object
javax.crypto.spec.PBEParameterSpec
All Implemented Interfaces:
AlgorithmParameterSpec
public class PBEParameterSpec extends Object implements AlgorithmParameterSpec
This class specifies the set of parameters used with password-based encryption (PBE), as defined in the PKCS #5 standard.
Since:
1.4

  • Constructor Details

    • PBEParameterSpec

      public PBEParameterSpec(byte[] salt, int iterationCount)
      Constructs a parameter set for password-based encryption as defined in the PKCS #5 standard.
      Parameters:
      salt - the salt. The contents of salt are copied to protect against subsequent modification.
      iterationCount - the iteration count.
      Throws:
      NullPointerException - if salt is null.

    • PBEParameterSpec

      public PBEParameterSpec(byte[] salt, int iterationCount, AlgorithmParameterSpec paramSpec)
      Constructs a parameter set for password-based encryption as defined in the PKCS #5 standard.
      Parameters:
      salt - the salt. The contents of salt are copied to protect against subsequent modification.
      iterationCount - the iteration count.
      paramSpec - the cipher algorithm parameter specification, which may be null.
      Throws:
      NullPointerException - if salt is null.

      public int getIterationCount()
      Returns the iteration count.
      Returns:
      the iteration count

    • getParameterSpec

      public AlgorithmParameterSpec getParameterSpec()
      Returns the cipher algorithm parameter specification.
      Returns:
      the parameter specification, or null if none was set.
