Understanding the algorithm used behind the BLOB concept

As part of our application design, we are storing customer data (for one hour) in a single table under BLOB column to reduce the DB hits and to improve the performance.

Recently we got below questions from my security team to understand on BLOB,

- How secure is BLOB

- What is the logic/algorithm used behind BLOB concept.

_ BLOB column data can be extracted by any tools apart from PEGA.

- How are encryption keys managed (how are they protected and where do they live)?

Thanks,

Gopi
