When SSL_write is called again after SSL_ERROR_WANT_..., it must get exactly the same buffer because parts of the buffer contents may already have been encrypted and wait in interal buffers while others may not yet have been looked at. What's really important is that buffer *contents* stay the same, but as a sanity check to avoid application bugs the OpenSSL library checks whether the buffer *address* is not changed. This check can be disabled by setting SSL_MODE_ACCEPT_MOVING_WRITE_BUFFER for that SSL object, using SSL_set_mode (or SSL_CTX_set_mode on the SSL_CTX before SSL_new is called). I don't know about Net::SSLeay, but it would not surprise me if the same string can be at a different memory location when SSL_write is called again. If so, look if SSL_set_mode is available; and you might want to ask the Net::SSLeay maintainers to consider always setting SSL_MODE_ACCEPT_MOVING_WRITE_BUFFER if the library default doesn't work for it. ______________________________________________________________________ OpenSSL Project http://www.openssl.org User Support Mailing List [EMAIL PROTECTED] Automated List Manager [EMAIL PROTECTED]
