The IV has to be randomly chosen for every encryption under the same key to achieve semantic security. It doesn't have to be secret, so you can simply send it along with the ciphertext. It's common to prepend it to the ciphertext and slice it off before decryption. It is bet...

It is important to understand the main differences between asymmetric and symmetric key encryption. Symmetric key encryption algorithms are computationally fast compared to asymmetric encryption algorithms (like RSA). However, since the same secret key is used for symmetric encryption and decryption, we ...
The above is the java encryption process, but the key bit 20. If I change the key to 16 bits, the following can be correctly decrypted; but if it is 20 bits, it cannot be decrypted properly. varbizContent='{"serialNumber":"330503JD05000018060401001YDQBWEG","status":38}';varkeyUtf8=...
DBMS_CRYPTO contains basic cryptographic functions and procedures. To use this package correctly and securely, a general level of security expertise is assumed.The DBMS_CRYPTO package enables encryption and decryption for common Oracle datatypes, including RAW and large objects (LOBs), such as images...
