openssl ssl encryption
- by deddihp
Hello, I want to discuss about openssl write and read method. Assume I have an data structure like below:
/-----------------------------------------------------\
| my_header | PAYLOAD |
\-----------------------------------------------------/
| |
\ / \ /
not encrypted encrypted
I think the proper algorithm would be like this :
SEND:
build my_header with my own header.
encrypt PAYLOAD with encryption function
attach my_header and PAYLOAD (encrypted) to one buffer
send it using common POSIX function just like send or sendto
RECV:
using common POSIX function just like recv or recvfrom.
extract my_header and PAYLOAD(encrypted)
decrypt PAYLOAD with decryption function
at last i got my_header and PAYLOAD(decrypted).
How is your approach if you face a problem like above. Since openssl encrypt all of data that is sent to SSL_write function (CMIIW).
Thanks
