Cryptographic Library - Client Central

Cryptographic functions natively in the ABAP environment

Data Security and protection of Intellectual property has become a necessity in the digital world. The software industry has settled on a number of security standards to protect against cyber attacks, namely AES and RSA. These standards are freely available for use in development projects outside of the SAP environment, but there is no pre-delivered ABAP component that provides this functionality to SAP customers.

Code is signed during transport creation and verified before activation to ensure that no tampering has occurred.

AES symmetric block encryption

Encryption/Decryption based on pass-phrases, salt and IV values
Key sizes: 128, 192, 256
Padding Scheme: CBC, ECB
Supports data streams of unlimited size

RSA asymmetric key encryption (Private/Public keys)

Encryption/Decryption
Sign/Verify data streams of unlimited size
Generation of new key pairs
Saving/Loading of PEM format files
- Plain Public/Private key PEM formats, including X.509 Certificates and encrypted Private key PEM files.
