=head1 DESCRIPTION
|
||
|
|
|
||
|
|
These functions convert OpenSSL objects to and from their ASN.1/string
|
||
|
|
representation. This function is used for B<X509v3> extensions.
|
||
|
|
|
||
|
|
=head1 NOTES
|
||
|
|
|
||
|
|
The letters B<i> and B<s> in B<i2s> and B<s2i> stand for
|
||
|
|
"internal" (that is, an internal C structure) and string respectively.
|
||
|
|
So B<i2s_ASN1_IA5STRING>() converts from internal to string.
|
||
|
|
|
||
|
|
It is the caller's responsibility to free the returned string.
|
||
|
|
In the B<i2s_ASN1_IA5STRING>() function the string is copied and
|
||
|
|
the ownership of the original string remains with the caller.
|
||
|
|
|
||
|
|
=head1 RETURN VALUES
|
||
|
|
|
||
|
|
B<i2s_ASN1_IA5STRING>() returns the pointer to a IA5 string
|
||
|
|
or NULL if an error occurs.
|
||
|
|
|
||
|
|
B<s2i_ASN1_IA5STRING>() return a valid
|
||
|
|
B<ASN1_IA5STRING> structure or NULL if an error occurs.
|
||
|
|
|
||
|
|
B<i2s_ASN1_INTEGER>() return a valid
|
||
|
|
string or NULL if an error occurs.
|
||
|
|
|
||
|
|
B<s2i_ASN1_INTEGER>() returns the pointer to a B<ASN1_INTEGER>
|
||
|
|
structure or NULL if an error occurs.
|
||
|
|
|
||
|
|
B<i2s_ASN1_OCTET_STRING>() returns the pointer to a OCTET_STRING string
|
||
|
|
or NULL if an error occurs.
|
||
|
|
|
||
|
|
B<s2i_ASN1_OCTET_STRING>() return a valid
|
||
|
|
B<ASN1_OCTET_STRING> structure or NULL if an error occurs.
|
||
|
|
|
||
|
|
B<i2s_ASN1_ENUMERATED>() return a valid
|
||
|
|
string or NULL if an error occurs.
|
||
|
|
|
||
|
|
B<s2i_ASN1_ENUMERATED>() returns the pointer to a B<ASN1_ENUMERATED>
|
||
|
|
structure or NULL if an error occurs.
|
||
|
|
|
||
|
|
B<s2i_ASN1_UTF8STRING>() return a valid
|
||
|
|
B<ASN1_UTF8STRING> structure or NULL if an error occurs.
|
||
|
|
|
||
|
|
B<i2s_ASN1_UTF8STRING>() returns the pointer to a UTF-8 string
|
||
|
|
or NULL if an error occurs.
|
||
|
|
|
||
|
|
=head1 HISTORY
|
||
|
|
|
||
|
|
i2s_ASN1_UTF8STRING() and s2i_ASN1_UTF8STRING() were made public in OpenSSL 3.0.
