Environment variable referenced in OSGI config doesn't work for multiline RSA PRIVATE KEY

When directly hardcoding the privateKey value into the OSGi configuration, it functions correctly. However, when attempting to use an environment variable in Adobe Cloud Manager to store and reference the same privateKey value, the application fails with an error message.

Below value works in OSGI - Notice "\r\n\" characters for new line

{

privateKey: "-----BEGIN RSA PRIVATE KEY----\r\n\BsdfdsfjdsewedXAfah1g74bNyrxY31ewqewZ3caLDngewqedwFp01RvhewjewD\r\nKOlwvUreUK6dBbnOvrewqeWw5yMFewoYFaPeksMFSRXC7Sreewed3w6WoewqeO+R4KDSHU/Yi9P\r\nPHvH6bfVwew957eqwegrUvuIb/CBYUGg4S3R6I/zNAJeewemeSJr344XAGxewqe6hIkZA/i/boW013\r\nLl1dXMyNqxwt6SZBcmeX/6FJUi6Fcebhba5aLnWkLF1036MfMsh\r\ncoXqs1kXtgfj0XJlIcH+T7rP0xJjIdTIjaPoQVeG+sKzWhRoRHjSaQehwendshadsadhsadsadj==\r\n-----END RSA PRIVATE KEY-----\r\n"

}

Now, when i store the above value in the variable(pvtKey) in the AEM cloud manager, and reference in OSGI config, it doesn't work. I have replaced \r\n\ with space.Getting following error. I have verified multiple times to ensure value is same.

{

privateKey: "$[env.pvtKey]"

}

The error is java.io.IOException: -----END RSA PRIVATE KEY not found

Hi @mohanjo1,
The issue you're facing is caused by how environment variables handle newlines. When you directly hardcoded the private key in the OSGi configuration, the \r\n characters were preserved, which is the correct format for a PEM encoded private key.

However, replacing the \r\n with spaces in the environment variable disrupts the format. The error message "java.io.IOException: -----END RSA PRIVATE KEY not found" indicates that the code cannot find the ending delimiter for the private key because the newlines are missing.

Don't replace the \r\n characters with spaces. Update your logic to store the private key value in the environment variable pvtKey while preserving the newlines. You can achieve this using escaping or raw string literals depending on your programming language.

If still the above solution doesn't work, the double quotes might treat the entire string as a literal. The env.pvtKey part wouldn't be interpreted as an environment variable reference.
Above solution shall work fine if OSGi configuration format allows plain string substitution.
Ensure your environment variable pvtKey is set correctly with the private key value, preserving the \r\n characters.

HI @kapil_rajoria can you please share an example with an osgi value and corresponding environment variable value. May be you can format my private key to make it compatible with environment variable. Just an fyi, I m reading that osgi config in java servlet where it's throwing an exception. I have pasted the osgi and enviornment value below.

Private key in OSGI- it works

Hi, check the below link:
https://medium.com/@toimrank/aem-as-a-cloud-service-osgi-configuration-secret-and-environment-variables-667a0ddfb1d5
Make sure you have made all the files. Please share the value of your_service.getPvtKey() method by using the debugger/loggers. Also, you can try breaking the string in several parts and see what part is causing problem.

As a solution hasn't been found yet, I've raised a ticket with Adobe. I'll update here once I receive a resolution. Until then, I'll keep this ticket open.

If a question lacks a definitive answer, it should be left open. It's inappropriate to label it as "correctly answered" merely because there's a single reply. My goal is to ensure that questions aren't marked as "answered" just for the sake of it. Ideally, the correct answer should be identified and appropriately acknowledged by the individual who posed the question.

I've observed this pattern in numerous questions where they're marked as "correctly answered" despite lacking the accurate solution."

Please bring the entire key in a single line. Remove all \r\n.

The Private Key should work now. Something like this

-----BEGIN RSA PRIVATE KEY----BsdfdsfjdsewedXAfah1g74bNyrxY31ewqewZ3caLDngewqedwFp01RvhewjewDKOlwvUreUK6dBbnOvrewqeWw5yMFewoYFaPeksMFSRXC7Sreewed3w6WoewqeO+R4KDSHU/Yi9PPHvH6bfVwew957eqwegrUvuIb/CBYUGg4S3R6I/zNAJeewemeSJr344XAGxewqe6hIkZA/i/boW013Ll1dXMyNqxwt6SZBcmeX/6FJUi6Fcebhba5aLnWkLF1036MfMshcoXqs1kXtgfj0XJlIcH+T7rP0xJjIdTIjaPoQVeG+sKzWhRoRHjSaQehwendshadsadhsadsadj==-----END RSA PRIVATE KEY-----

@aanchal-sikka I've observed that your suggestion involves removing all line breaks and condensing the content into a single line without any spaces. I'm unsure whether this approach will be effective. Given that we're modifying the private key, there's a concern that the server may not be able to decrypt it correctly. Have you tested this approach before to ensure its compatibility and functionality?

Yes, We have used the similar approach with AEM & Adobe IO integration.
