I have problems using the RSA_public_encrypt function, since it always
return -1
(by the way, the return value is the length of the envrypted data, isn't
it?)
Since I've compiled openssl 0.9.5a in debug mode (as a static library on
Windows NT), I was able to observe this sequence of calls:
RSA_public_encrypt,
rsa->meth->rsa_pub_enc(flen, from, to, rsa, padding),
RSA_eay_public_encrypt(int flen, unsigned char *from, unsigned char *to, RSA
*rsa, int padding),
RSA_padding_add_PKCS1_type_2(buf,num,from,flen),
RAND_bytes(p,j),
rand_meth->bytes(buf,num).
The latest functions detect an entropy less than needed and sets the ''ok''
to false (actually, NON TRUE), so that at the end of the function, the
following branch is executed:
...
RANDerr(RAND_F_SSLEAY_RAND_BYTES,RAND_R_PRNG_NOT_SEEDED);
return(0);
...
Consequently, all calling functions fail.
Is this a bug or am I (probably) missing something?
Thanks in advance
