    • An apparatus for hash cryptography has a hardware structure that is capable of providing both secure hash algorithm (SHA)-1 hash calculation and SHA-256 hash calculation. The apparatus for hash cryptography generates a plurality of first message data corresponding to a plurality of first rounds when the SHA-1 hash calculation is performed and generates a plurality of second message data corresponding to a plurality of second rounds when the SHA-256 hash calculation is performed by using one memory, one first register, one XOR calculator, and one OR calculator, calculates a message digest by the SHA-1 hash calculation by using the plurality of first message data when the SHA-1 hash calculation is performed, and calculates a message digest by the SHA-256 by using the plurality of second message data when the SHA-256 hash calculation is performed.
    • 用于散列加密的装置具有能够提供安全散列算法(SHA)-1哈希计算和SHA-256哈希计算的硬件结构。 当执行SHA-1散列计算时,用于散列加密的装置产生对应于多个第一轮的多个第一消息数据,并且当SHA-256散列计算时产生与多个第二轮相对应的多个第二消息数据 通过使用一个存储器,一个第一寄存器,一个XOR计算器和一个OR计算器,当执行SHA-1哈希计算时,通过使用多个第一消息数据通过SHA-1哈希计算来计算消息摘要,以及 当执行SHA-256哈希计算时,通过使用多个第二消息数据,通过SHA-256计算消息摘要。
