MD5 (Message-Digest Algorithm 5)

MD5 (Message-Digest Algorithm 5)
MD5 is a cryptographic hash function widely used with 128-bit hash value. MD5 is used for security applications and for testing the integrity of a file.
Step-making MD5:
1. The addition of bits booster -> Message plus booster sejaumlah bit so that the message length congruent to 448 modulo 512. Long-bit booster is between 1 to 512.
2. Value Addition of Long Messages -> messages that have been given a booster bits with 64 bits plus a stated length of the original message. So the message length is now a multiple of 512 bits
3. Initialize MD Buffer -> MD5 requires 4 pieces of each buffer length of 32 bits. Fourth this buffer holds the intermediate results and final results
4. Processing messages in the block is 512 bits -> message is divided into blocks whose length x fruit each 512 bits. Each block of 512 bits processed together with MD into the output buffer 128 bits. This process is called the process HMD5
How it Works MD5
MD5 512-bit processing block is divided into 16 subblok size 32 bits. Algorithm output is set into 4 blocks each measuring 32-bit after combined will form a 128 bit hash value.
