Thanks mkl and andreas. The example code helps me a bit. Basically, I use the rangestream to calculate my own hash. Instead of the standard itext example of using the Java Signature to do both create the hash and sign the hash, I want to create the hash on my own and find a different way to sign the hash against my certificate. I think this one little part steps outside of the scope of itext though. But I do need to ask here what do i need to input into the PdfPKCS7 setExternalDigest() after i find a way to sign the pdf hash? -- View this message in context: http://old.nabble.com/Signing-from-hash%2C-not-rangestream.-tp26585481p26618807.html Sent from the iText - General mailing list archive at Nabble.com.
