Online Text & File Checksum Calculator This page lets you hash ASCII text or a file with many different hash algorithms. Checksums are commonly used to verify the integrety of data. The most common use is to verify that a file has been downloaded without error. The data you enter here is 100% private, neither the data nor hash values are ever recorded. Enter some ASCII or UNICODE text.

Checksum Generator Generating Checksums and Digests The Checksum Generator allows users to generate checksums and digests for an entire document or a selection within a document and is started by select 'Generate Checksum.' From the 'Tools' menu or by pressing the checksum button on either the main Tools toolbar or checksum toolbar (located on the Checksum tab of the Results Window). Users can select the desired algorithms and configure CRC parameters for Custom CRCs prior to pressing the 'Generate' button to calculate the checksums and digests. All calculations are performed on the active document with Hex Workshop.

Checksum and Digest Algorithms The Checksum Generator supports 23 checksum and digests variations: Algorithm Bytes Description Checksum (8 bit) 1 Simple count where all the bytes are added in an 8 bit accumulator. Initial value is 0. Checksum (16 bit) 2 Simple count where all the bytes are added in an 16 bit accumulator. Initial value is 0. Checksum (32 Bit) 4 Simple count where all the bytes are added in an 32 bit accumulator.

On-line CRC calculation. Free CRC routines downloadable. Javascript sourced, No limits, Covers CRC-16, 32, CCITT, DNP and Sick routines.

Initial value is 0. Checksum (64 bit) 8 Simple count where all the bytes are added in an 64 bit accumulator.

Initial value is 0. CRC (16 Bit) 2 16 bit Cyclic Redundancy Check (CRC) with a polynomial of 0x8005 and an initial value of 0x0000. CRC/CCITT (16 bit) 2 16 bit Cyclic Redundancy Check (CRC) with a polynomial of 0x1021 and an initial value of 0xFFFF. CRC (32 bit) 4 32 bit Cyclic Redundancy Check (CRC) with a polynomial of 0x04C11DB7 and an initial value of 0xFFFFFFFF. Custom CRC (16 bit) 2 16 bit Cyclic Redundancy Check (CRC) with a user supplied polynomial and initial value. Custom CRC (32 bit) 4 32 bit Cyclic Redundancy Check (CRC) with a user supplied polynomial and initial value.
