If you have used PartitionMagic (provided with Mandrake Linux) to partition the hard disk or install Linux on one of the two drives, you do not need to run the fips program. However, if you have two hard drives, you can use Windows to format the second drive. 　　 Internal Shift: Smooth Transition 　　 After Linux is installed, you may feel overwhelmed.

algorithm, which has been developed and improved by cryptographic experts for many years, and has now become one of the most secure hashing algorithms and is widely used. The idea of the algorithm is to receive a piece of plaintext, and then convert it into a paragraph (usually smaller) ciphertext in an irreversible way, or simply to take a string of input codes (called Pre-mapping or information) and convert them to shorter lengths, A fixed number of bits of output sequence is the process of h

(); returnhex.encodehexstring (s); }SHASecure Hash algorithm is primarily intended for digital Signature algorithm DSA, which is defined in the digital Signature standard DSS. For messages that are less than 2^64 bits in length, SHA1 produces a 160-bit message digest. The algorithm has been developed and improved by cryptographic experts for many years and is widely used. The idea of the algorithm is to receive a piece of plaintext, and then convert it into a paragraph (usually smaller) ciphert
