ID: 32772 User updated by: ivan at mishanin dot ru Reported By: ivan at mishanin dot ru Status: Bogus Bug Type: OpenSSL related Operating System: Windows XP, Windows 2000 Server PHP Version: 5.0.4 New Comment: after openssl_private_encrypt($res,$crypttext,$prkeyid); openssl_error_string(); return null. but sometimes it openssl_error_string(); return error:0406C06E:rsa routines:RSA_padding_add_PKCS1_type_1:data too large for key size i use just one key and use just one text, i don't understand why it sometime return error:0406C06E:rsa routines:RSA_padding_add_PKCS1_type_1:data too large for key size and sometime return null, null is return more often. Previous Comments: ------------------------------------------------------------------------ [2005-04-19 23:59:41] sniper@php.net Try using openssl_error_string(); after those functions and you'll get more detailed information WHY they fail. ------------------------------------------------------------------------ [2005-04-19 17:38:33] ivan at mishanin dot ru Description: ------------ When i try to encrypt big string it return null. If i try to use big key to encrypt - it help my, but if i use a big sting (300 000 signs) - it isn't work. i try encrypt big string by part, it's ok, but then i try to decrypt it - openssl_public_decrypt make a null decrypt text... certificate is OK - under MS BizTolk server it's work right. Reproduce code: --------------- prkeyid = openssl_pkey_get_private("file://c:/cert/CAkey.pem", '1234'); $pubkeyid = openssl_pkey_get_public("file://c:/cert/CAcert.pem"); openssl_private_encrypt($res,$crypttext,$prkeyid); $fp = fopen ("c:/file.xml", "w+"); // for test fwrite ($fp, $crypttext); fclose ($fp); openssl_public_decrypt($crypttext, $ext_data, $pubkeyid); $fp = fopen ("c:/file2.xml", "w+"); fwrite ($fp, $ext_data); fclose ($fp); Actual result: -------------- null ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=32772&edit=1
