Hi everyone,
I'm trying to verify a pdf signature using the same code that is at
http://itextpdf.sourceforge.net/howtosign.html#howtoverify
http://itextpdf.sourceforge.net/howtosign.html#howtoverify and I get the
following error:
java.security.NoSuchAlgorithmException: 1.2.840.113549.1.1.1 MessageDigest
not available
at sun.security.jca.GetInstance.getInstance(GetInstance.java:142)
at java.security.Security.getImpl(Security.java:659)
at java.security.MessageDigest.getInstance(MessageDigest.java:129)
at com.lowagie.text.pdf.PdfPKCS7.<init>(PdfPKCS7.java:310)
at
com.lowagie.text.pdf.AcroFields.verifySignature(AcroFields.java:1838)
at
com.lowagie.text.pdf.AcroFields.verifySignature(AcroFields.java:1794)
...
I'm using:
- JDK1.6u12
- iText 2.1.4
- bouncyCastle version 1.41 for jdk1.6
I changed the provider BC for SUN and I get the same error. I read others
post and may be is a enviroment problem or compatibility between the used
libraries.
If someone has a solution...
thanks...
