[openssl-users] EVP_Encrypt/EVP_Decrypt input/output buffers requirements

[Patrice Guérin]

Hello to all,

Documentation does not provide input/output buffers requirements for 
encryption/decryption, so
is it safe to submit the same buffer (ie, input=output) for these 
operations ?
If not, what is the minimum distance 'd' required (input = output+d) ?
This is to be used in small memory environment.

Thank you.
Kind regards,
Patrice.
