All game packages are signed with the ECDSA signature. The public key for it can be found in '''download_plugin.prx''' or in '''nas_plugin.prx''' (this also applies to NPDRM SELFs). Usually game packages are signed with two signatures - one for the header and the other for the entry table. | |||

The last 0x20 bytes of the package contains a hash (sha1sum) of the package (sha1 of the whole file minus the last 0x20 bytes). Or in other words... to verify the integrity of a package is needed to crop the 0x20 bytes at the end, then calculate the sha1 of the resulting file, then compare with the sha1 that was cropped | |||
Is also used as part of the package identification info inside the '''TITLE_ID-ver.xml''' files in PSN servers that lists the available game patches for each game. See: [[Online_Connections#Game_Updating_Procedure|Game Updating Procedure]] page and the '''sha1sum''' in the .xml examples | |||
