1=pod 2 3=head1 NAME 4 5d2i_SSL_SESSION, d2i_SSL_SESSION_ex, i2d_SSL_SESSION - convert SSL_SESSION object from/to ASN1 representation 6 7=head1 SYNOPSIS 8 9 #include <openssl/ssl.h> 10 11 SSL_SESSION *d2i_SSL_SESSION(SSL_SESSION **a, const unsigned char **pp, 12 long length); 13 SSL_SESSION *d2i_SSL_SESSION_ex(SSL_SESSION **a, const unsigned char **pp, 14 long length, OSSL_LIB_CTX *libctx, 15 const char *propq); 16 int i2d_SSL_SESSION(SSL_SESSION *in, unsigned char **pp); 17 18=head1 DESCRIPTION 19 20These functions decode and encode an SSL_SESSION object. 21For encoding details see L<d2i_X509(3)>. 22 23SSL_SESSION objects keep internal link information about the session cache 24list, when being inserted into one SSL_CTX object's session cache. 25One SSL_SESSION object, regardless of its reference count, must therefore 26only be used with one SSL_CTX object (and the SSL objects created 27from this SSL_CTX object). 28 29=head1 RETURN VALUES 30 31d2i_SSL_SESSION() and d2i_SSL_SESSION_ex() return a pointer to the newly 32allocated SSL_SESSION object. 33In case of failure the NULL-pointer is returned and the error message 34can be retrieved from the error stack. 35 36i2d_SSL_SESSION() returns the size of the ASN1 representation in bytes. 37When the session is not valid, B<0> is returned and no operation is performed. 38 39=head1 SEE ALSO 40 41L<ssl(7)>, L<SSL_SESSION_free(3)>, 42L<SSL_CTX_sess_set_get_cb(3)>, 43L<d2i_X509(3)> 44 45=head1 HISTORY 46 47The function d2i_SSL_SESSION_ex() was added in OpenSSL 3.2. 48 49=head1 COPYRIGHT 50 51Copyright 2001-2024 The OpenSSL Project Authors.
