d2i_SSL_SESSION.3ssl - Man Page

convert SSL_SESSION object from/to ASN1 representation

Synopsis

 #include <openssl/ssl.h>

 SSL_SESSION *d2i_SSL_SESSION(SSL_SESSION **a, const unsigned char **pp,
                              long length);
 int i2d_SSL_SESSION(SSL_SESSION *in, unsigned char **pp);

Description

These functions decode and encode an SSL_SESSION object. For encoding details see d2i_X509(3).

SSL_SESSION objects keep internal link information about the session cache list, when being inserted into one SSL_CTX object's session cache. One SSL_SESSION object, regardless of its reference count, must therefore only be used with one SSL_CTX object (and the SSL objects created from this SSL_CTX object).

Return Values

d2i_SSL_SESSION() returns a pointer to the newly allocated SSL_SESSION object. In case of failure the NULL-pointer is returned and the error message can be retrieved from the error stack.

i2d_SSL_SESSION() returns the size of the ASN1 representation in bytes. When the session is not valid, 0 is returned and no operation is performed.
