Encryption & Decryption for PostgreSQL (Command-Line)
Hello Everyone, Today lets see how to encrypt and decrypt the data using pgcrypto extension. Encryption and decryption are important aspects of database security. In this blog post, we will explore how to encrypt and decrypt data in PostgreSQL using command-line tools. First, let's discuss the basics of encryption and decryption. Encryption is the process of converting plaintext data into a ciphertext format that can only be read by authorized users. Decryption is the reverse process of converting ciphertext data back into its original plaintext format. PostgreSQL supports several encryption and decryption functions that can be used to secure your data. One of the most popular encryption methods in PostgreSQL is the pgcrypto extension, which provides several cryptographic functions that can be used to encrypt and decrypt data. Now lets see how to encrypt and decrypt the data at column level using pgcrypto extension. 1. First lets create a sample database named eminds using command...
