C# RSA encryption-decryption with my own key

C# RSA encryption-decryption SHA256 1024bit with my own private key, public key — generated with cmd or PowerShell on OpenSSL or RSACryptoServiceProvider XML.

OpenSSL generates the private key and public key.

Example1

1.Create RSA private key 1024

>openssl genrsa -out rsa-private.txt 1024

2.Create RSA public key with private key

>openssl rsa -in .\rsa-private.txt -out rsa-public.txt -pubout -outform PEM

You got a result 2 file in the directory (rsa-private.txt & rsa-public.txt)

Now we will be coding with encryption-decryption

Output

Done!

=======================================

RSACryptoServiceProvider XML

Example2

Frist create RSA public key and private key XML

You got a result to be like this and write file on the path in class StreamWriter

Second, encrypt and decrypt string follow my code below

RUN

Done!
