Cripto_AES_128_GCM

The project contains the following pieces:

• A parameterized entry point specifying the necessesary details for the program
• Two classes, one that resolv the input parameters, and the other, that work with OpenSSL's EVP functions to encrypt/ decrypt
• The exemple files I've worked with

Input parameters: -in, -out, -key, -iv, -aad.

• -in specifies that the following parameter represents the name of the input file.
• -out specifies that the following parameter represents the name of the output file.
• -key specifies that the following parameter represents the name of the file that contains the key.
• -iv specifies that the following parameter represents the name of the file that contains the IV.
• -aad specifies that the following parameter represents the name of the file that contains the AAD.

Implementation details:

• If the -in is omitted, the program requires user input (from STD_IN);
• If the -out is omitted, the program will save the output in a file called data.enc (Was given while thinking about the encryption procces, but is the same for decryption too...)
• If the -key is omitted, the program requires input from STD_IN, also for -iv.
• If the -aad is omitted, the program encrypt/decrypt data without AAD.
