Encrypt given data using des-ede3-cfb1 cipher algo. Triple DES (DES-EDE3) in CFB1 mode, where only one bit of feedback is used to encrypt data one bit at a time. CFB1 mode was developed to handle fine-grained encryption of small data units while using Triple DES for enhanced security. Triple DES in CFB1 mode is more secure than single DES but still considered outdated due to its slow performance and vulnerability to modern attacks. Our encryption process prepends the IV string used during the encryption process in the encrypted data so that it can be used during decryption.
