获取“ java.lang.SecurityException”

Question

I have a project in which I have these jars:

• bcprov-ext-jdk15-141.jar
• bcprov-jdk15-141.jar
• bcmail-jdk14-136.jar

Problem

Now I am using itextpdf-5.5.9.jar with bcprov-jdk15on-1.50.jar to generate password protected PDF but the problem is if I remove old bc jars it works fine but I have other code dependencies which uses previous 3 jars.

So if I keep these old jar I get

java.lang.SecurityException: class "org.bouncycastle.asn1.ASN1Primitive"'s signer information does not match signer information of other classes in the same package.

I think these jars are conflicting can anyone suggest some solution.

Answer 1

If you are using maven, just use the following dependency and it will automatically add the required org.bouncycastle » bcpkix-jdk15on 1.49 and org.bouncycastle » bcprov-jdk15on 1.49 automatically.

<dependency>
    <groupId>com.itextpdf</groupId>
    <artifactId>itextpdf</artifactId>
    <version>5.5.9</version>
</dependency>

If you are not using maven then try using 1.49 org.bouncycastle jars.
