[openssl-users] Doubt about the CMS_sign() function (in file openssl/crypto/cms/cms_smime.c)
Hi folks, My name is Luiz Laranjeira. I am an associate professor of software engineering with the University of Brasilia, Brazil. I have a group that is developing a signer and validator according to RFC 5652 (CMS/PKCS#7) and we are using OpenSSL. I would like to ask your help concerning a doubt we have: Does the CMS_sign(...) function return a full CMS/PKCS#7 object coded in ASN1 according to RFC 5652 or does it return simply the digital signature field (encrypted hash of the data plus the signed attributes) in ASN1 format? I'd appreciate your assistance with this issue. Best regards, Luiz Laranjeira ___ openssl-users mailing list To unsubscribe: https://mta.openssl.org/mailman/listinfo/openssl-users
Re: data size issue with SSL_read( ) / SSL_write
Hi
does your server send \r\n with hello?
i read byte by byte until i found an \r\n
Regards
Luiz
Hello,
In my programm, client send HELLO message to server.
1)
---
SSL_write is encapsulated in MY_send( ) function like this :
MY_send(MY_cn sd, const char* data, size_t len) {
ret = SSL_write(socki-ssl, data, len);
}
and MY_send is encapsuled in MYsend like this :
int MYApi::MYsend(SIP_cn sd, const std::string data)
{
return MY_send(sd, data.data(), data.size());
}
in python code, I call :
api.MYsend(sock, HELLO)
2)
---
SSL_read is encapsulated in MY_recv( ) function like this :
MY_recv(MY_cn sd, char* buf, size_t* len, unsigned int flags, unsigned
int
timeout) {
SSL_read(socki-ssl, buf, *len);
}
and MY_recv is encapsuled in MYrecv like this :
int MYApi::MYrecv(MY_cn sd, const std::string data)
{
strresult *r = new strresult;
const size_t L=8*1024;
size_t len = L;
char buf[L];
r-first = MY_recv(sd, buf, len, flags, timeout);
if (!r-first)
r-second.assign(buf, len);
return r;
}
in python code, I call
err,data = api.MYrecv(cn, 0, 0)
The problem :
when I print data, I have got :
HELLO��y0�y
0�y��y
i`�0�y
��� ���L���L��-M
etc...
instead of
HELLO.
in MYrecv, when I make L = 5, it works
what should I do to read just the right size so that when I print I get
HELLO, GOODBYE, etc ... and not HELLO��y0�y,
GOODBYE��y0�y etc ...
thanks for your help

Re: Does OpenSSL supports the HTTP POST request?
Hi I use https post with any problem you just need to format properly your https post string , and send the data Regards Luiz Hi, I want to use HTTP POST request for connecting to the server..I checked with the available sample programs but it all supports HTTP GET. So my doubt is that Is it possible to send HTTP POST message using the openSSL. If yes?then how I can achieve that?

Re: [FWD] SSL_write returned SSL_ERROR_SSL
Hi
I use to write data to openssl the follow function
int hb_inetSSLWrite(int com,SSL* pSSL, int timeout, char * msg, int
length, int* iRet)
{
int ret;
int sslerr;
int r;
fd_set fd_r, fd_w;
struct timeval tv;
do
{
ret = SSL_write(pSSL, msg, length);
sslerr = SSL_get_error(pSSL, ret);
if ( ret 0)
{
r = 1;
*iRet = 0;
break;
}
*iRet = sslerr;
FD_ZERO( fd_r );
FD_ZERO( fd_w );
if( timeout 0 )
{
tv.tv_sec = timeout / 1000;
tv.tv_usec = ( timeout % 1000 ) * 1000;
}
switch (sslerr)
{
case SSL_ERROR_WANT_READ:
FD_SET(com,fd_r);
break;
case SSL_ERROR_WANT_WRITE:
FD_SET(com,fd_w);
break;
default:
return -1;
}
if( timeout 0 )
r = select(com+1,fd_r,fd_w,NULL,tv);
else
r = select(com+1,fd_r,fd_w,NULL,NULL);
} while ( ret == -1 r != 0 );
if ( r == 0)
return -1;
return ret;
}

I am facing some weird problem in SSL_write(). Most of the times it
returned with SSL_ERROR_SSL.
Can anyone explain what is this error and how can we fix this.
I am using 0.9.8g openssl version.
Any assistance (including temporary workarounds) appreciated.
Thanks

SSL_read/SSL_write and select
Dear Friends
How to use properly SSL_read/SSL_write with select?
my default code with use standart api, make an call to select before call to
recv/send api
my code to read is like this
to Read i use
do
{
if( iPos == iAllocated - 1 )
{
iAllocated += iBufferSize;
Buffer = ( char * ) hb_xrealloc( Buffer, iAllocated );
}
if( hb_selectReadSocket( Socket ) )
{
iLen = SSL_read( Socket-pSSL, cChar, 1 );
iRet = SSL_get_error( Socket-pSSL, iLen) ;
Socket-errorCode = iRet;
}
else
{
iTimeElapsed += Socket-timeout;
/* this signals timeout */
iLen = -2;
}
if( iLen 0 )
{
/* verify endsequence recognition automata status */
if( cChar == szPattern[ ulPatPos ] )
{
ulPatPos ++;
if( ! szPattern[ ulPatPos ] )
{
break;
}
}
else
{
ulPatPos = 0;
}
Buffer[ iPos++ ] = cChar;
}
else
{
break;
}
}
while( iMax == 0 || iPos iMax );
static int hb_selectReadSocket( HB_SSL_SOCKET_STRUCT *Socket )
{
fd_set set;
struct timeval tv;
FD_ZERO( set );
FD_SET(Socket-com, set);
if( Socket-timeout == -1 )
{
if( select( Socket-com + 1, set, NULL, NULL, NULL ) 0 )
return 0;
}
else
{
tv.tv_sec = Socket-timeout/ 1000;
tv.tv_usec = (Socket-timeout % 1000) * 1000;
if( select( Socket-com + 1, set, NULL, NULL, tv ) 0 )
return 0;
}
return FD_ISSET( Socket-com, set );
}
So , how can i change so can work correctly with openssl SSL_read/SSL_write
api
Thanks in advance
Regards
Luiz Rafael
