Hello, I am writing an application where I need to do encryption in place, on a data which is splitted on multiple buffers, avoiding the solution where everything is copied in one big buffer, encrypted and then copied back. I want to use the EVP interface and not lower level functions.
I am using the EVP interface with Blowfish as encryption algorithm. I wrote a very simple test program where EVP_EncryptUpdate (each of the calls encrypts 16 bytes) is called two consecutive times, followed by an EVP_EncryptFinal which addes 8 more bytes, so the total size is 40 bytes. Decryption is done in a similar manner, EVP_Decrypt update called twice and then Decrypt Final. However, the first EVP_DecryptUpdate called on the first 16 bytes returns 8 when decrypting so in the end the EVP_DecryptFinal fails. Any ideas what might be the problem? thanks, -- Cristina ______________________________________________________________________ OpenSSL Project http://www.openssl.org User Support Mailing List [EMAIL PROTECTED] Automated List Manager [EMAIL PROTECTED]
