Several versions of the TLS protocol exist. SSL 2.0 is a deprecated [27] protocol version with significant weaknesses. SSL 3.0 (1996) and TLS 1.0 (1999) are successors with two weaknesses in CBC-padding that were explained in 2001 by Serge Vaudenay. [28]
OpenSSL is a software library for applications that provide secure communications over computer networks against eavesdropping, and identify the party at the other end. It is widely used by Internet servers, including the majority of HTTPS websites.
Oracle APEX can be run inside Oracle Database Express Edition (XE), a free entry-level database. Although the functionality of APEX isn't intentionally limited when running on XE, the limitations of the database engine may prevent some APEX features from functioning. Furthermore, Oracle XE has limits for CPU, memory, and disk usage. [20]
In cryptography, a padding oracle attack is an attack which uses the padding validation of a cryptographic message to decrypt the ciphertext. In cryptography, variable-length plaintext messages often have to be padded (expanded) to be compatible with the underlying cryptographic primitive .

Padding oracle attacks can be avoided by making sure that an attacker cannot gain knowledge about the removal of the padding bytes. This can be accomplished by verifying a message authentication code (MAC) or digital signature before removal of the padding bytes, or by switching to a streaming mode of operation.
