Elliptic Curve certificate

[Muhammad Ibrahim]

Hi,

I was trying to sign a document using an EC certificate but it failed with Unknown Key Algorithm EC error.

Does EC certificates supported or will it be supported ?

SEVERE Problem occured
java.security.NoSuchAlgorithmException: Unknown Key Algorithm EC
        at com.lowagie.text.pdf.PdfPKCS7.<init>(PdfPKCS7.java:619)
        at net.sf.jsignpdf.SignerLogic.signFile(SignerLogic.java:357)
        at net.sf.jsignpdf.SignerLogic.run(SignerLogic.java:116)
        at java.lang.Thread.run(Thread.java:748)

INFO Finished: Creating of signature failed.

Hi Muhammad,

could you try this SNAPSHOT version?
https://s01.oss.sonatype.org/content/repositories/snapshots/com/github/kwart/jsign/jsignpdf-distribution/2.2.0-SNAPSHOT/jsignpdf-distribution-2.2.0-20220306.154554-28.zip

I've enabled the ECDSA there. Still, I didn't verify the resulting signed PDFs.

The change is this commit in the OpenPDF library:

Hi Josef,

It worked.

Already tested and validate the resulting document with Adobe Acrobat Rader and it did not complain.

Thank you very much.
