The private key is faster than the public key. |
It is slower than a private key. |
2. |
In this, the same key (secret key) and algorithm are used to encrypt and decrypt the message. |
In public-key cryptography, two keys are used, one key is used for encryption, and the other is used for decryption. |
3. |
In private key cryptography, the key is kept a secret. |
In public-key cryptography, one of the two keys is kept a secret. |
4. |
The private key is Symmetrical because there is only one key that is called a secret key. |
The public key is Asymmetrical because there are two types of keys: private and public keys. |
5. |
In this cryptography, the sender and receiver need to share the same key. |
In this cryptography, the sender and receiver do not need to share the same key. |
6. |
In this cryptography, the key is private. |
In this cryptography, the public key can be public and a private key is private. |
7. |
It is an efficient technology. |
It is an inefficient technology. |
8. |
It is used for large amounts of text. |
It is used for only short messages. |
9. |
There is the possibility of losing the key that renders the systems void. |
There is less possibility of key loss, as the key is held publicly. |
10. |
The private key is to be shared between two parties. |
The public key can be used by anyone. |
11. |
The Performance testing checks the reliability, scalability, and speed of the system. |
The Load testing checks the sustainability of the system. |
12. |
The private key is used in algorithms such as AES 128, AES 192 and AES 256. |
The public key is used in algorithms such as RSA, DSA, etc. |
13. |
The private key is kept secret. |
The public key is widely distributed. |
14. |
It is used to protect disk drives and other data storage devices. |
It is used to secure web sessions and emails. |
15. |
The recipient’s private key decrypts the message. |
The recipient’s public key encrypts the message. |
16. |
If the private key is the locking key, then the system can be used to verify documents sent by the holder of the private key. |
If the public key is the locking key, then it can be used to send private communication. |
