Hello students, to retain the confidentiality in the software, encryption is commonly used.
00:06
Encryption is the process of converting the information into the code or the cipher to prevent the unauthorized access, ensuring that only the authorized parties can access and understand the original data.
00:21
So there are different encryption techniques and the algorithms that are used to protect the sensitive information and maintain the confidentiality in the software application.
00:32
As some of the used encryption methods are as the symmetric encryption, where in this method the same key is used for both encryption and decryption, the key must be kept secret between the sender and the receiver.
00:57
For example, if the symmetric encryption algorithm includes the aes, that is the advanced encryption standard or des or the des or even the des of 3, triple des, whereas the next we consider as a asymmetric encryption, where in the public key encryption, it is nothing but the public key of the encryption, public key encryption, where the asymmetric encryption uses the pair of the values, a public key for the encryption and a private key of the decryption.
01:59
The public key can be openly shared with the private key remains secret.
02:04
The data encrypted with the public key can only be decrypted using the corresponding private values.
02:11
Example of the asymmetric encryption algorithm includes the rsa and an elliptical curve cryptography.
02:20
So as the next is the hybrid encryption, hybrid encryption, where here the hybrid encryption, it is the combined both the symmetric and asymmetric encryption, it uses the symmetric encryption to encrypt the data and then uses an asymmetric encryption to encrypt the symmetric data.
02:49
This approach combines the efficiency of the symmetric combination with the security of the asymmetric encryption.
02:58
As the next is the end -to -end encryption, end -to -end encryption, where this is the communication method where the data is encrypted on the sender side and decrypted on the receiver side...
