Error:0308010c:Digital Envelope Routines::Unsupported

What is a Digital Envelope?

A digital envelope is a security mechanism used in cryptography to protect data during transmission. It combines symmetric and asymmetric encryption methods to ensure the confidentiality and integrity of the data.

1. Symmetric Encryption: This method uses the same key for both encryption and decryption. It is efficient for encrypting large amounts of data.
2. Asymmetric Encryption: This involves a pair of keys—a public key for encryption and a private key for decryption. It is used to securely exchange symmetric keys.

Error Breakdown
