WebbSM4 is a two-way encryption algorithm. When you use this algorithm, you must provide keys to encrypt data on the database server. Precautions The pgcrypto function runs on the database server. Data and keys are transmitted in plaintext between the client and pgcrypto. To ensure data security, we recommend that you use SSL to encrypt data. http://netinfo-security.org/CN/10.3969/j.issn.1671-1122.2024.08.003 fishman powerbridge piezo pickup https://benwsteele.com
