![]() ![]() The same applies to other programming languages, and byte streams are recommended. Reading with a character stream not only requires byte conversion, but is also prone to errors. The title here requires two words to form 16 bits. Calculate file and folder hashes with MD5, SHA1, SHA256, SHA384 and SHA512 protocols. Regarding file reading: It is recommended to use byte stream reading, because String in java is 2 bytes, which is 16 bits. ![]() If the result is 0, keep it otherwise, discard the datagram. When the receiver accepts it, it will calculate the checksum again. The sender will bring the checksum when sending the datagram. Steps: The first part of the datagram is summed by word (16 bits) in one's complement operation, and the obtained sum is the checksum after the inverted code. The principle of checksum is the checksum of the IP datagram header, and its calculation uses a 16-bit binary complement summation algorithm. Checksum Calculator is a feather-light and portable application you can use to calculate the CRC32 checksums of multiple files at the same time. If the checksum is greater than 16 bits, then the carry is added to the final checksum. In order to calculate the verification sum, the sending computer treats each pair of characters as a 16-bit integer and calculates the verification sum. The checksum is the c-bit remainder that results from the division operation In other words, you divide the augmented message by the generator polynomial, discard the quotient, and use the remainder as your checksum. The figure below shows the calculation of 16-bit verification and a small string.
