WebApr 11, 2024 · A private key is a cryptographic key used in an encryption algorithm to both encrypt and decrypt data. These keys are used in both public and private encryption: In private key encryption, also known as symmetric encryption, the data is first encrypted using the private key and then decrypted using the same key. WebAug 26, 2016 · With AES-CBC you usually need a random IV. However, in the case where you use each key only once, like when using password-based encryption with random salts for each file, you can use a fixed, zero IV. So as long as you use a new salt for each file – and even new versions of the same file – you can forgo storing an IV and just use a zero block.
