SAP S/4HANA Error 710: Invalid Asymmetric Cipher
Description
This error indicates that an unsupported asymmetric encryption cipher was used or attempted to be used within an SQL operation or secure data process in SAP S/4HANA. It specifically states that only RSA-OAEP-2048 is currently supported for asymmetric cryptography. This typically occurs during secure data operations, data encryption/decryption, or secure communication setup when the configured cipher does not match the required standard.
Error Message
ERR_SQL_INV_ASYMMETRIC_CIPHER Currently only RSA-OAEP-2048 is supported: invalid cipher
Known Causes
3 known causesIncorrect Cipher in SQL Statement
An SQL statement or database function attempted to use an asymmetric encryption cipher other than RSA-OAEP-2048, which is the only supported algorithm.
Database Security Configuration Mismatch
The database or application security settings are configured to use an unsupported asymmetric cipher for encryption/decryption operations.
Third-Party System Cipher Incompatibility
A third-party system or integration attempting secure communication with SAP S/4HANA is configured to use an incompatible asymmetric encryption cipher.
Solutions
3 solutions available1. Verify and Correct Cipher Configuration in SAP System medium
Ensure that the cryptographic library and its configuration within the SAP system are set to use the supported RSA-OAEP-2048 cipher.
1
Access SAP system using SAP GUI.
2
Navigate to transaction code `STRUST`. This transaction is used for managing the trust manager and security settings.
3
In the `STRUST` transaction, locate the PSE (Personal Security Environment) nodes. Pay close attention to any PSEs related to SSL Server Standard, SSL Client Standard, or specific application PSEs that might be involved in asymmetric encryption.
4
Examine the configuration for the relevant PSE. Look for settings related to 'Cipher Suites' or 'Algorithm' for SSL/TLS connections. Ensure that only the supported cipher suite, typically including RSA-OAEP-2048, is enabled or that the unsupported ones are disabled.
5
If the configuration is incorrect, modify it to include `RSA-OAEP-2048` and remove any unsupported ciphers. The exact steps for modification will depend on the specific PSE and the available options within `STRUST`.
6
Save the changes made in `STRUST`.
7
Restart the relevant SAP application server instances or the entire SAP system to apply the changes. This is crucial for the new cryptographic configurations to take effect.
2. Update SAP Cryptographic Library (SAPCRYPTOLIB) advanced
Ensure that the SAP cryptographic library used by your S/4HANA system is up-to-date and supports the required cipher.
1
Identify the current version of the SAP Cryptographic Library installed on your S/4HANA application servers. This information can often be found in the SAP system logs or by checking the library files directly on the operating system.
Example command to check library version (may vary by OS and installation path):
`./sapgenpse -v`2
Consult SAP Notes related to `ERR_SQL_INV_ASYMMETRIC_CIPHER` and SAP Cryptographic Library. These notes will specify the minimum required version of SAPCRYPTOLIB that supports `RSA-OAEP-2048`.
3
Download the latest compatible version of the SAP Cryptographic Library from the SAP Software Download Center. Ensure you select the correct version for your operating system and S/4HANA release.
4
Follow the SAP documentation for updating the SAP Cryptographic Library. This typically involves replacing the existing library files on all relevant application servers.
5
Restart the SAP application server instances or the entire SAP system after the library update.
3. Review and Adjust Application-Specific Security Settings medium
Check if the specific SAP application or module encountering this error has its own security or cryptographic settings that might be overriding system defaults.
1
Identify the specific SAP application, transaction, or interface that triggers the `ERR_SQL_INV_ASYMMETRIC_CIPHER` error.
2
Consult the SAP documentation for that specific application module to understand its cryptographic requirements and configuration options. Look for parameters related to encryption, SSL/TLS, or data protection.
3
Access the relevant configuration transactions or tables for that application. This might involve transactions like `SM30` to maintain views or custom configuration transactions.
4
If the application has specific cipher suite settings, ensure they are compatible with `RSA-OAEP-2048` or that they are not forcing the use of an invalid cipher. Adjust these settings as per the application's documentation.
5
Save any changes made to the application's security configuration.
6
Restart the application server instances or the specific application services if applicable.
