The EPUB or electronic publication format is formally standardized in ISO/IEC TS 30135. Its structure is an extension of XHTML and XML and has optional support for cascaded style sheets. The format allows for documents that contain images either in raster or vector graphics format. Digital rights management is also supported.
Many other common filename extensions use the ZIP format in one aspect or another, for example JAR, .WAR, .DOCX, .XLXS, .PPTX, .ODT, .ODS, .ODP all utilize the ZIP format. The ZIP format provides for data integrity through the CRC32 specification with support for digital signatures. It also supports multiple compression algorithms but commonly utilizes the DEFLATE algorithm.
