I suggest you rely on the documentation instead. The normal way to do things is to call EVP_EncryptInit_ex() initially, then call EVP_EncryptUpdate() one or more times on each chunk to be encrypted and finally call EVP_EncryptFinal_ex() when all data has been handled. That example seems to be calling EVP_EncryptFinal_ex() on each chunk. Steve. -- Dr Stephen N. Henson. Email, S/MIME and PGP keys: see homepage OpenSSL project core developer and freelance consultant.
