Java Apns Certificate Error with "Derinputstream.Getlength(): Lengthtag=109, Too Big."

Java APNS Certificate Error with DerInputStream.getLength(): lengthTag=109, too big.

I had the same problem but my solution will help you only if you are using maven.

Maven resource filtering (that let's you include variables in your resource files) can mess up your binaries - and certificates are especially sensitive to modification.

In general, binary content shouldn't be filtered. But I couldn't just simply disable resource filtering because I have some .properties files that include variables. So the solution was to exclude .p12 files from filtering.

<build>
    [...]
    <resources>
        <resource>
            <directory>src/main/resources</directory>
            <filtering>true</filtering>
            <excludes>
                <exclude>**/*.p12</exclude>
            </excludes>
        </resource>
        <resource>
            <directory>src/main/resources</directory>
            <filtering>false</filtering>
            <includes>
                <include>**/*.p12</include>
            </includes>
        </resource>
    </resources>
    [...]
</build>

PKCS#12 : DerInputStream.getLength() exception

I had this problem and I've searched the depths of google and still couldn't find the answer. After some days battling with a terrible quality legacy code, I found what was causing this error.

KeyStore.load(InputStream is, String pass);

this method takes an InputStream and if there's any problem with such InputStream, this exception is thrown, some problems that I've encountered:

• The InputStream points to the wrong / blank / just created file
• The InputStream is already open or something else is holding the resource
• The InputStream was already used and read, thus the position of the next byte of InputStream is it's end

The last one was the responsible for my problem. The code was creating an InputStream from a certificate, and proceeding to use it in two KeyStore.load() calls, the first one was successful, the second one always got me this error.

grails apns plugin : SSLHandshakeException

It was a certificate issue , after generating another .p12 file it finally worked :)
