NAME
RSA_sign_ASN1_OCTET_STRING, RSA_verify_ASN1_OCTET_STRING - RSA signatures
LIBRARY
libcrypto, -lcrypto
SYNOPSIS
#include
int RSA_sign_ASN1_OCTET_STRING(int dummy, unsigned char *m,
unsigned int m_len, unsigned char *sigret, unsigned int *siglen,
RSA *rsa);
int RSA_verify_ASN1_OCTET_STRING(int dummy, unsigned char *m,
unsigned int m_len, unsigned char *sigbuf, unsigned int siglen,
RSA *rsa);
DESCRIPTION
_R_S_A___s_i_g_n___A_S_N_1___O_C_T_E_T___S_T_R_I_N_G_(_) signs the octet string mm of size
mm__lleenn using the private key rrssaa represented in DER using PKCS #1
padding. It stores the signature in ssiiggrreett and the signature size
in ssiigglleenn. ssiiggrreett must point to RRSSAA__ssiizzee((rrssaa)) bytes of
memory.
dduummmmyy is ignored.
The random number generator must be seeded prior to calling _R_S_A___s_i_g_n___A_S_N_1___O_C_T_E_T___S_T_R_I_N_G_(_).
_R_S_A___v_e_r_i_f_y___A_S_N_1___O_C_T_E_T___S_T_R_I_N_G_(_) verifies that the signature ssiiggbbuuff
of size ssiigglleenn is the DER representation of a given octet string
mm of size mm__lleenn. dduummmmyy is ignored. rrssaa is the signer's
public key.
RETURN VALUES
_R_S_A___s_i_g_n___A_S_N_1___O_C_T_E_T___S_T_R_I_N_G_(_) returns 1 on success, 0 otherwise.
_R_S_A___v_e_r_i_f_y___A_S_N_1___O_C_T_E_T___S_T_R_I_N_G_(_) returns 1 on successful verification, 0
otherwise.
The error codes can be obtained by _E_R_R___g_e_t___e_r_r_o_r(3).
BUGS
These functions serve no recognizable purpose.
