The text to be transmitted securely will be encrypted, not by public key cryptography, but by using SYMMETRIC key encryption. This is typically a 128 bit cipher, but can be greater. Symmetric key methods need both sites to use the same key. To do this one site must at some stage origina...

Systems and method for implementing an encryption technique by combining matrix mathematics, audio frequencies, and symmetric key. Data encryption/decryption may be performed using symmetric key based implementations, with the encryption keys being derived from unique sequences of frequencies (e.g., ...

Under the hood, GnuPG generates a symmetric key for each message, because public-key cryptography is expensive for large messages; the public key algorithm is only used to encrypt the symmetric key and to sign a digest of the file. You should follow this model. Using AES for symmetric ...
Decryption: When the ciphertext or message is received, the receiver would be able to decode the ciphertext into plaintext by using the key provided to them by the sender. FernetFernet is a symmetric encryption technique available to users in the cryptography module in Python that makes it eas...

“Encryption is a mathematical process that takes plain text and calculates ciphertext using complex mathematical algorithms that are practically impossible to reverse without the original encryption key,”Kingstonencrypted business manager Richard Kanadjian explains. Encryption can be symmetric, where the sa...
