How do you decrypt a string?

Decrypt a string according to given rules

1. Start with the first character of the original string.
2. In every odd step, append the next character to it.
3. In every even step, prepend the next character to the encrypted string so far.

How do I encrypt a string?

Steps:

1. Import rsa library.
2. Generate public and private keys with rsa.
3. Encode the string to byte string.
4. Then encrypt the byte string with the public key.
5. Then the encrypted string can be decrypted with the private key.
6. The public key can only be used for encryption and the private can only be used for decryption.

What is encryption and decryption in C?

Encryption mainly processes the original content through an algorithm to make the original content invisible. The decryption process usually needs to know the encryption algorithm, and then reverse process the encrypted content to realize the decryption function.
