-Status: Open
+Status: Bogus
Bug Type: OpenSSL related
Operating System: RedHat 8.0 Kernel 2.4.20
PHP Version: 4.3.9
New Comment:
That's the way that RSA works; you need to create a bigger key to be
able to encrypt bigger chunks of data; the error message is quite
clear.
Not a PHP bug.

Description:
------------
This function can't encrypt large data when data length more than key
size
I get error :
encrypt error : string(84) "error:0406D06E:rsa
routines:RSA_padding_add_PKCS1_type_2:data too large for key size"
Reproduce code:
---------------
$privkey = openssl_pkey_new();
$csr = openssl_csr_new($GLOBALS["_CONFIG"]["key_dn"],
$privkey);
$sscert = openssl_csr_sign($csr, null, $privkey, 365);
openssl_csr_export($csr, $csrout);
openssl_x509_export($sscert, $public_key ) ;
openssl_pkey_export($privkey, $private_key);
$log_data="B,1,1,1,1,1234,0001,AAA012,0001,0008,0000,0005,Y,Y,Y,Y,0779,071504,S1,PP01,M01,20040715073,1B,1,1,1,1,1234,0001,AAA012,0001,0007,0000,0006,Y,Y,Y,Y,0679,071504,S1,PP01,M01,200407150843,2B,1,1,1,1,1234,0001,AAA015,0002,0005,0000,0008,Y,Y,Y,Y,0899,071504,S1,PP01,M01,200407150856,3B,1,1,1,1,1234,0001,AAA015,0001,0004,0000,0009,Y,Y,Y,Y,1199,071504,S1,PP01,M01,200407150857,4";
$PK = openssl_get_publickey( $server_public_key );
if(!openssl_public_encrypt($log_data , $crypttext , $PK ))
{
echo "encrypt error : " ;
var_dump(openssl_error_string() );
}
