DESCRIPTION

34       These functions convert OpenSSL objects to and from their ASN.1/string
35       representation. This function is used for X509v3 extensions.
36

NOTES

38       The letters i and s in i2s and s2i stand for "internal" (that is, an
39       internal C structure) and string respectively.  So i2s_ASN1_IA5STRING()
40       converts from internal to string.
41
42       It is the caller's responsibility to free the returned string.  In the
43       i2s_ASN1_IA5STRING() function the string is copied and the ownership of
44       the original string remains with the caller.
45

RETURN VALUES

47       i2s_ASN1_IA5STRING() returns the pointer to a IA5 string or NULL if an
48       error occurs.
49
50       s2i_ASN1_IA5STRING() return a valid ASN1_IA5STRING structure or NULL if
51       an error occurs.
52
53       i2s_ASN1_INTEGER() return a valid string or NULL if an error occurs.
54
55       s2i_ASN1_INTEGER() returns the pointer to a ASN1_INTEGER structure or
56       NULL if an error occurs.
57
58       i2s_ASN1_OCTET_STRING() returns the pointer to a OCTET_STRING string or
59       NULL if an error occurs.
60
61       s2i_ASN1_OCTET_STRING() return a valid ASN1_OCTET_STRING structure or
62       NULL if an error occurs.
63
64       i2s_ASN1_ENUMERATED() return a valid string or NULL if an error occurs.
65
66       s2i_ASN1_ENUMERATED() returns the pointer to a ASN1_ENUMERATED
67       structure or NULL if an error occurs.
68
69       s2i_ASN1_UTF8STRING() return a valid ASN1_UTF8STRING structure or NULL
70       if an error occurs.
71
72       i2s_ASN1_UTF8STRING() returns the pointer to a UTF-8 string or NULL if
73       an error occurs.
