How to use OpenSSL in windows for encryption and decryption ?
First, download OpenSSL for Windows from a reputable source. Here is a good place to start: https://wiki.openssl.org/index.php/Binaries
After installing OpenSSL, open a command prompt. You can chose among the many algorithms, but if you dont know what you want, going with AES-256 in CBC mode is a good start.
C:\Users\admin>openssl aes-256-cbc -a -salt -in file.txt -out encrypted-file.txt.enc enter aes-256-cbc encryption password: Verifying - enter aes-256-cbc encryption password: C:\Users\admin>type encrypted-file.txt.enc U2FsdGVkX19v2JTUzRF/BRwy7egsmi+4A1KXyJfQmBF70cg0Go+EvroxvXd8ugiI C:\Users\admin>openssl aes-256-cbc -d -a -in encrypted-file.txt.enc -out decrypted-file.txt enter aes-256-cbc decryption password:
I hope this helps you get started.
