FontChecksum is a Java software that checks OpenType and TrueType font files' internal checksums. It's compatible with version 1.4 of Java.
At times, files that are downloaded or copied from worn CDs/DVDs can end up different from the original. This problem becomes even more complicated when you end up with two files that have the same size, date, and apparent contents. At this point, it's challenging to tell which of these files is correct.
However, with FontChecksum, this process becomes simple. By comparing byte-by-byte with commands like "comp" on DOS/Windows or "cmp" on UNIX, you can quickly find the differences between the two files. Furthermore, FontChecksum uses the internal checksums within the font file to determine which file is more accurate.
It's worth noting that freeware and shareware fonts made with older font tools often have numerous checksum errors. For more information, please refer to the PDF documentation included in the ZIP file. FontChecksum is an open-source program and has been released under the GNU General Public License.
Overall, FontChecksum is an essential tool for anyone who regularly downloads and shares font files. It provides a simple yet powerful way to test which of the two files you have is more correct. Highly recommended!
