Condition for Encrypt and Decrypt data using RSA in Java
Description: RSA encryption and decryption use a pair of keys , a public key for encryption and a private key for decryption. The encryption process involves using the recipient’s public key to transform plaintext into ciphertext. The recipient can then use their private key to decrypt the ciphertext back into the original plaintext. RSA relies on the mathematical difficulty of factoring large prime numbers, making it a secure method for data transmission. The public key is shared openly, while the private key is kept confidential. RSA encryption typically operates on small chunks of data, and for larger datasets, symmetric encryption algorithms like AES are often used in combination with RSA. The RSA algorithm provides confidentiality by ensuring that only the holder of the private key can decrypt the data that was encrypted with the corresponding public key. The strength of RSA encryption increases with larger key sizes, typically ranging from 1024 to 4096 bits, where larger key sizes offer stronger security but require more computational resources.

To start the encryption process, select the input file path after setting up the RSA encryption GUI.
Step 2
The choosen file location is indicated by the selected file path that shows up in the text field.
Step 3
Select the path of the 'Encrypt.txt' file to begin the encryption process.
Step 4
The path of the 'Encrypt.txt' file has been selected for encryption.
Step 5
The files Encrypt.txt and input.txt are chosen. When the Encrypt button is clicked, encryption is successfully finished.
Step 6
To start the decryption process, select the input file path after setting up the RSA decryption GUI.
Step 7
The chosen file location is indicated by the selected file path that shows up in the text field.
Step 8
Select the path of the 'Decrypt.txt' file to begin the decryption process.
Step 9
The path of the 'Decrypt.txt' file has been selected for decryption.
Step 10
The files Encrypt.txt and Decrypt.txt are chosen. When the Decrypt button is clicked, decryption is successfully finished.
Step 11
RSA uses a public key for encryption and a private key for decryption. The public key shares with anyone, while the private key stays secure.
Step 12
Encryption applies to the input text file, with the result saved in the encrypt text file. Decryption restores the original content from the decrypt text file.
