Hot Network Questions OpenSSL 1.1.0 and above performs the dependency step for you, so you should not see the message. However, you should perform a make clean to ensure the list of objects files is accurate after a reconfiguration. Configure Options . OpenSSL has been around a long time, and it carries around a lot of cruft. Sep 01, 2001 · OpenSSL uses an abstraction called a BIO object for input and output. This allows the programmer to use the same functions for different kinds of I/O channels (sockets, terminal, memory buffers, etc.) merely by using different kinds of BIO objects. If you create a mem bio using BIO_new_mem_buf(), the memory is considered read-only: BIO_new_mem_buf() creates a memory BIO using len bytes of data at buf, if len is -1 then the buf is assumed to be nul terminated and its length is determined by strlen. The BIO is set to a read only state and as a result cannot be written to. Client error: ERROR: SSL(2006F078) BIO_read: uninitialized. The application works exactly as expected with OpenSSL < 1.1.0, running for many hours without any issues. In contrast, with OpenSSL 1.1.0c, you run into such errors after about 20 minutes of running the test case, often sooner. I hope the above is useful for you to reproduce the issue. May 13, 2018 · Indeed, ../libcrypto.so does not export BIO_f_zlib and does not compile the files in crypto/comp/, where BIO_f_zlib is defined. But the code in env.c requires BIO_f_zlib(), as ZLIB is defined. While removing zlib-shared after ./Configure does help, ./Configure is supposed to fail when impossible combinations are used.
BIO_new_buffer_ssl_connect()creates a new BIOchain consisting of a buffering BIO, an SSL BIO(using ctx) and a connect BIO. BIO_ssl_copy_session_id()copies an SSLsession id between BIOchains fromand to. locating the SSLBIOs in each chain and calling SSL_copy_session_id()on the internal SSLpointer.
BIO_gets() performs the BIOs "gets" operation and places the data in buf. Usually this operation will attempt to read a line of data from the BIO of maximum length len. There are exceptions to this however, for example BIO_gets() on a digest BIO will calculate and return the digest and other BIOs may not support BIO_gets() at all. Heavy October 1, 2009 at 8:03 am. Hi I had some trouble with the openssl base 64 de/encoding too. This was because openssl does no 'pure' base64 encoding by default but uses the pem standard base64 encoding scheme ( this is why adding the lines from roxas will make it work in the most cases because the newlines are ignored ) but if you want to decode base64 that is used inside a certificate or Jul 10, 2020 · I think here BIO_set_close(bio, BIO_NOCLOSE) means openssl will not free memory under bufferPtr, even after BIO_free_all(bio), so (*bufferPtr).data is safe to use. But, user must free it manually, or it will cause memory leak.
BIO_set_fd() sets the socket of BIO b to fd and the close flag to close_flag. BIO_get_fd() places the socket in c if it is not NULL, it also returns the socket. If c is not NULL it should be of type (int *). BIO_new_socket() returns a socket BIO using sock and close_flag. Notes. Socket BIOs also support any relevant functionality of file
