these functions are declared and implemented using macros.
crypto/rsa/rsa.h contains the declarations
DECLARE_ASN1_ENCODE_FUNCTIONS_const(RSA, RSAPublicKey)
DECLARE_ASN1_ENCODE_FUNCTIONS_const(RSA, RSAPrivateKey)
the macro itself is in crypto/asn1/asn1.h
#define DECLARE_ASN1_ENCODE_FUNCTIONS_const(type, name) \
type *d2i_##name(type **a, const unsigned char **in, long len); \
int i2d_##name(const type *a, unsigned char **out); \
DECLARE_ASN1_ITEM(name)
the macro for the implementation is in crypto/rsa/rsa_asn1.c
IMPLEMENT_ASN1_ENCODE_FUNCTIONS_const_fname(RSA, RSAPrivateKey, RSAPrivateKey)
IMPLEMENT_ASN1_ENCODE_FUNCTIONS_const_fname(RSA, RSAPublicKey, RSAPublicKey)
it's defined in crypto/asn1/asn1t.h as
#define IMPLEMENT_ASN1_ENCODE_FUNCTIONS_const_fname(stname, itname, fname) \
stname *d2i_##fname(stname **a, const unsigned char **in, long len) \
{ \
return (stname *)ASN1_item_d2i((ASN1_VALUE **)a, in, len,
ASN1_ITEM_rptr(itname));\
} \
int i2d_##fname(const stname *a, unsigned char **out) \
{ \
return ASN1_item_i2d((ASN1_VALUE *)a, out, ASN1_ITEM_rptr(itname));\
}
In other words: You're basically looking for ASN1_item_d2i() and
ASN1_item_i2d(), respectively.
Best regards,
Martin
