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

i2s_ASN1_UTF8STRING() and s2i_ASN1_UTF8STRING() were made public in
OpenSSL 3.0.
