Hi,
I'm having an exception during verification of PDF signed by Adobe Acrobat
8.0. I'm using JDK1.5.0_06 and iText2.0.
The exception is as follows:
ExceptionConverter: java.security.NoSuchAlgorithmException:
SHA1with1.2.840.113549.1.1.11 Signature not available
at java.security.Signature.getInstance(Signature.java:208)
at com.lowagie.text.pdf.PdfPKCS7.<init>(PdfPKCS7.java:326)
at
com.lowagie.text.pdf.AcroFields.verifySignature(AcroFields.java:1739)
at
com.lowagie.text.pdf.AcroFields.verifySignature(AcroFields.java:1695)
Please guide me in this regard as I'm successful to verify PDF, signed with
older version of Adobe Acrobat e.g. 7.x, 6.x and 5.x.
Regards,
KS
