Asymmetric Key Operations with the DBMS_CRYPTO Package

The DBMS_CRYPTO package provides four functions that enable you to perform asymmetric key operations for encryption, decryption, signing, and verification.

Asymmetric key operations (also called public key cryptography) use a public key and private key to encrypt and decrypt a message in order to protect it from unauthorized access.

The asymmetric key operation functions are as follows:

• PKDECRYPT decrypts RAW data using a private key assisted with key algorithm and encryption algorithm.

• PKENCRYPT encrypts RAW data using a public key assisted with key algorithm and encryption algorithm.

• SIGN signs RAW data using a private key assisted with key algorithm and sign algorithm

• VERIFY verifies RAW data using signature, public key assisted with key algorithm and sign algorithm.
