A digest is a character frequency table that is calculated for certain characters within a rendered HTML page. If an HTML document is contained within a frame set, text is verified only for the frame that contains the selected text, not the entire page.
The following sample code (in bold) is generated automatically for HTML digest verifications:
const HTML_DIGEST_1 := "\h01910000000011D063032CCB7D023EFBBD02000000000000000000000000000000001 602010601010703010108010503020201" "\h03010201030502010105010403070103010205050402060107050102"; transaction TMain begin ...
