Overview
Data Encryption helps protect sensitive data at rest by concealing it from unauthorized users in the event of a breach. This is achieved by scrambling the content into an unreadable format based on encryption and decryption keys. Typically speaking, this data pertains to PII (Personally Identifiable Information), which is sensitive information such as credit card numbers and other information related to an identifiable person.
Users encrypt their data on a column basis by specifying column_name
in the encryption syntax.
The demand for confidentiality has steadily increased to protect the growing volumes of private data stored on computer systems and transmitted over the internet. To this end, regulatory bodies such as the General Data Protection Regulation (GDPR) have produced requirements to standardize and enforce compliance aimed at protecting customer data.
SQream enables customers to implement a-Symmetric Encryption solution using Secret Keys that they provide and manage themselves. The chosen encryption algorithm is AES-256, known for its strength and security. It is crucial to ensure that the Secret Key length is precisely 256 bits or 32 bytes.
