hi all:
I want to use private key to encrypt a message,
and decrypt with public key.
i know there is PK11_PubDecryptRaw, PK11_PubEncrptRaw,
but all these don't do padding things(PKCS1) for
me.
and SGN_*(), VFY_*(), PK11_Verify*() give me the
digest message, not plaint message i want.
i find PK11_PubEncryptPKCS1() in mailing list
discussion, which seems to do the padding. But
i want to use private key to encrypt, not
public key. And what's more, there are not any
doc or example codes to show PK11_PubEncryptPKCS1()
usage
because i use PK11_PubEncryptPKCS1() in my code guessing
howto use, but i got 8192 error(PR_GetError()), i lookup
the error code:
An I/O error occurred during authentication; or
an error occurred during crypto operation (other than signature
verification).
all the description is senseless for me
following is my code:
modulus_len = modulus_len = SECKEY_PublicKeyStrength(lf_sec->pubkey);
char *data_buf = calloc(...modulus_len);
char *enbuf = calloc(...,modulus_len);
PK11_PubEncryptPKCS1(lf_sec->pubkey,enbuf,tmpbuf,modulus_len,NULL);
...
use the same parameters for PK11_PubEncryptRaw() will work well
can anyone give me some examples or hints? thanks
in advance
