Re: [openssl-users] error making Private RSA
I have solved my create public RSA problem with this code: printf( "Method 1\n" ); RSA* RSA1 = RSA_new(); RSA* RSA2 = RSA_new(); RSA2->n = RSA1->n = My_RSA->n; RSA2->e = RSA1->e = My_RSA->e; RSA2->d = RSA1->d = My_RSA->d; RSA2->p = RSA1->p = My_RSA->p; RSA2->q = RSA1->q = My_RSA->q; RC = PEM_write_bio_RSAPublicKey( bio, RSA1 ) ; printf( "%d RC: %d\n", __LINE__, RC ); RC = PEM_write_bio_RSAPrivateKey( bio, RSA2, NULL, NULL, 0, NULL, NULL ) ; printf( "%d RC: %d\n", __LINE__, RC ); if( !RSA1 ) printf( RED " ERROR: Could not load Public KEY!\n" " PEM_read_bio_RSA_PUBKEY FAILED:\n %s\n" OFF, ERR_error_string( ERR_get_error(), NULL ) ) ; else Check_Key( RSA1, ";" ); if( !RSA2 ) printf( RED " ERROR: Could not load Private KEY!\n" " PEM_read_bio_RSA_PUBKEY FAILED:\n %s\n" OFF, ERR_error_string( ERR_get_error(), NULL ) ) ; else Check_Key( RSA2, ";" ); -- William Estrada Mt Umunhum, CA, USA, Earth HTTP:// Mt-Umunhum-Wireless.net Skype: MrUmunhum -- William Estrada Mt Umunhum, CA, USA, Earth HTTP:// Mt-Umunhum-Wireless.net Skype: MrUmunhum -- William Estrada Mt Umunhum, CA, USA, Earth HTTP:// Mt-Umunhum-Wireless.net Skype: MrUmunhum -- openssl-users mailing list To unsubscribe: https://mta.openssl.org/mailman/listinfo/openssl-users
Re: [openssl-users] error making Private RSA
I have been tiring to keep my posting to a minim but I am not getting
across what I am looking to
fix. And I have been getting reports that my source code is not
viewable. In my Apache logs I see that some people have be using the
wrong link, they are tiring to use
"http://mt-umunhum-wireless.net/mt-umunhum-wireless.net/Sources;
This is wrong! use:
"http://mt-umunhum-wireless.net/Sources/rsa;
or
"216.173.131.138/Sources/rsa"
The most recent attempt is the rsapost.c with the output rsapost.txt
What I am attempting to do is:
1) generate a RSA key pair, working but always the same keys.
2) remove the public key, working
3) create a RSA structure with the public key, 4 methods, all fail.
4) use the public key to encrypt a sting, don't get here.
5) use the RSA pair to decrypt the string.
The code is not clean but here it is:

Not sure this is the proper way to use this mailing system? My source can be viewed at: mt-umunhum-wireless.net/Sources/rsa/rsa.c What version of openssl? I'm guessing 1.0.2. Put this line inyour code ERR_load_ERR_strings(); And youll get a more informative message.

error:2007507E:BIO routines:mem_write:write to read only BIO
BIO_new_mem_buf() gives you a read-only BIO. You probably want
BIO_new(BIO_s_mem()) instead.
See:
https://www.openssl.org/docs/man1.1.0/crypto/BIO_s_mem.html
Although, that error is coming from one of the PEM_write_bio_* calls
(which you are not checking the error return code of), so it doesn't
explain why RSA_check_key() fails. You don't show how you generate the
RSA structure to start with, so I guess you're not generating it properly.

[openssl-users] error making Private RSA
Hello group,
I am attempting to create a Private RSA structure with the following code:
BIO*
PEM = BIO_new_mem_buf( Key, Key_Len );
if( Type == 1 )
PEM_write_bio_RSAPrivateKey( PEM, RSA, NULL, NULL, 0, NULL, NULL );
else
PEM_write_bio_RSAPublicKey( PEM, RSA );
if( RSA_check_key( RSA ) != 1 ) {
printf( RED "Make %s RSA Failed\n" OFF, Type==1?"Private":"Public" );
int Error = ERR_get_error();
char *MSG = ERR_error_string( Error, NULL);
printf( "%s\n", MSG ); }
and I get this error:
Make Private RSA Failed
error:2007507E:lib(32):func(117):reason(126)
Can anyone tell me what this error is and how to fix it?
