# #9402 Fix RSA private key PEM import

> RSA private key import from PEM format now works correctly by using the proper RSA cryptographic service provider type instead of the base RSA type.

[Pull request](https://github.com/microsoft/BCApps/pull/9402) · merged into `main` (BC30) on 2026-07-17 by JesperSchulz · 3 files (+34 -4), 1 AL · fix · tier official · reviewed (checked by Opus)

## What changed

- Fixes a runtime failure when RSA.ToSecretXmlString is called with a PEM private key
- The PEM is now imported into the RSACryptoServiceProvider type that RSAEncryptionHelper.ImportFromPem requires
- PEM key material stays wrapped as SecretText outside the existing non-debuggable helper
- The test app gets friend access so it can reuse the internal PEM export helper
- A test was added for importing a private key from PEM. The public API is unchanged
- Behaviour changes for users or extensions.

## AL objects touched

- [Codeunit 1476 "RSA Impl."](../../objects/codeunit/1476.md), System Application: modified
