    Methods
    Modifier and Type | Method and Description
    --- | ---
    `static CipherParameters` | `makePBEMacParameters(BCPBEKey pbeKey, java.security.spec.AlgorithmParameterSpec spec)` generate a PBE based key suitable for a MAC algorithm, the key size is chosen according the MAC size, or the hashing algorithm, whichever is greater.
    `static CipherParameters` | `makePBEMacParameters(javax.crypto.spec.PBEKeySpec keySpec, int type, int hash, int keySize)` generate a PBE based key suitable for a MAC algorithm, the key size is chosen according the MAC size, or the hashing algorithm, whichever is greater.
    `static CipherParameters` | `makePBEParameters(BCPBEKey pbeKey, java.security.spec.AlgorithmParameterSpec spec, java.lang.String targetAlgorithm)` construct a key and iv (if necessary) suitable for use with a Cipher.
    `static CipherParameters` | `makePBEParameters(javax.crypto.spec.PBEKeySpec keySpec, int type, int hash, int keySize, int ivSize)` construct a key and iv (if necessary) suitable for use with a Cipher.
