直接已知子类:

PBES2Core.HmacSM3AndSM4_128_CBC_PKCS5Padding, PBES2Core.HmacSM3AndSM4_128_ECB_PKCS5Padding

abstract class PBES2Core
extends CipherSpi

This class represents password-based encryption as defined by the PKCS #5 standard. These algorithms implement PBE with HmacSHA1/HmacSHA2-family and AES-CBC. Padding is done as described in PKCS #5.
