19
21 RSA_sign_ASN1_OCTET_STRING() signs the octet string m of size m_len
22 using the private key rsa represented in DER using PKCS #1 padding. It
23 stores the signature in sigret and the signature size in siglen. sigret
24 must point to RSA_size(rsa) bytes of memory.
25
26 dummy is ignored.
27
28 The random number generator must be seeded prior to calling
29 RSA_sign_ASN1_OCTET_STRING().
30
31 RSA_verify_ASN1_OCTET_STRING() verifies that the signature sigbuf of
32 size siglen is the DER representation of a given octet string m of size
33 m_len. dummy is ignored. rsa is the signer's public key.
34
36 RSA_sign_ASN1_OCTET_STRING() returns 1 on success, 0 otherwise.
37 RSA_verify_ASN1_OCTET_STRING() returns 1 on successful verification, 0
38 otherwise.
39
40 The error codes can be obtained by ERR_get_error(3).

43 These functions serve no recognizable purpose.
