How to encrypt & decrypt large files using openssl

While encrypting large files using openssl, it gives large size error. My file to be encrypted size is more than 100 
bytes.

Thanks,
Manas

Re: How to encrypt & decrypt large files using openssl

I created a key using 

openssl genrsa -out private.key 1024

& used this key for encryption & decryption using -aes256

openssl enc -aes256 -e -pass file:/usr/bin/enc/private.key -in x1.xml -out x2.xml

openssl enc -aes256 -d -pass file:/usr/bin/enc/private.key -in x2.xml -out x3.xml

It works now.

Thanks & Regards,
Manas
