Description:
------------
I did this in command line php,
OpenSSL 0.9.8k 25 Mar 2009
If I create a csr with a UTF8 character, then I ought to get the UTF8 character out, untampered with when I parse it.
Test script:
---------------
<?php
function stringAsHex($string){$unpacked = unpack("H*", $string);return implode(" ", str_split($unpacked[1],2));}
$config = array("digest_alg" => "sha1","x509_extensions" => "v3_ca","req_extensions" => "v3_req","private_key_bits" => 2048,"private_key_type" => OPENSSL_KEYTYPE_RSA,"encrypt_key" => false,);
$csr_info = array(
"countryName" => "US",
"stateOrProvinceName" => "Utah",
"localityName" => "Lindon",
"organizationName" => "Chinese",
"organizationalUnitName" => "IT \xe4\xba\x92",
"commonName" => "www.example.com",);
$private = openssl_pkey_new($config);
$csr_res = openssl_csr_new($csr_info, $private);
openssl_csr_export($csr_res, $csr); //echo $csr;
$output = openssl_csr_get_subject($csr);
echo "A: ".$csr_info["organizationalUnitName"]."\n";
echo "B: ".stringAsHex($csr_info["organizationalUnitName"])."\n";
echo "C: ".$output['OU']."\n";
echo "D: ".stringAsHex($output['OU'])."\n";
Expected result:
----------------
A: IT 互
B: 49 54 20 e4 ba 92
C: IT 互
D: 49 54 20 e4 ba 92
Actual result:
--------------
A: IT 互
B: 49 54 20 e4 ba 92
C: IT äº
D: 49 54 20 c3 a4 c2 ba c2 92

I saved the csr that php generated... and the parsed it with: openssl asn1parse -in a.csr 0:d=0 hl=4 l= 687 cons: SEQUENCE 4:d=1 hl=4 l= 407 cons: SEQUENCE 8:d=2 hl=2 l= 1 prim: INTEGER :00 11:d=2 hl=2 l= 106 cons: SEQUENCE 13:d=3 hl=2 l= 11 cons: SET 15:d=4 hl=2 l= 9 cons: SEQUENCE 17:d=5 hl=2 l= 3 prim: OBJECT :countryName 22:d=5 hl=2 l= 2 prim: PRINTABLESTRING :US 26:d=3 hl=2 l= 13 cons: SET 28:d=4 hl=2 l= 11 cons: SEQUENCE 30:d=5 hl=2 l= 3 prim: OBJECT :stateOrProvinceName 35:d=5 hl=2 l= 4 prim: PRINTABLESTRING :Utah 41:d=3 hl=2 l= 15 cons: SET 43:d=4 hl=2 l= 13 cons: SEQUENCE 45:d=5 hl=2 l= 3 prim: OBJECT :localityName 50:d=5 hl=2 l= 6 prim: PRINTABLESTRING :Lindon 58:d=3 hl=2 l= 16 cons: SET 60:d=4 hl=2 l= 14 cons: SEQUENCE 62:d=5 hl=2 l= 3 prim: OBJECT :organizationName 67:d=5 hl=2 l= 7 prim: PRINTABLESTRING :Chinese 76:d=3 hl=2 l= 15 cons: SET 78:d=4 hl=2 l= 13 cons: SEQUENCE 80:d=5 hl=2 l= 3 prim: OBJECT :organizationalUnitName 85:d=5 hl=2 l= 6 prim: T61STRING :IT 互 93:d=3 hl=2 l= 24 cons: SET 95:d=4 hl=2 l= 22 cons: SEQUENCE 97:d=5 hl=2 l= 3 prim: OBJECT :commonName 102:d=5 hl=2 l= 15 prim: PRINTABLESTRING :www.example.com 119:d=2 hl=4 l= 290 cons: SEQUENCE 123:d=3 hl=2 l= 13 cons: SEQUENCE 125:d=4 hl=2 l= 9 prim: OBJECT :rsaEncryption 136:d=4 hl=2 l= 0 prim: NULL 138:d=3 hl=4 l= 271 prim: BIT STRING 413:d=2 hl=2 l= 0 cons: cont [ 0 ] 415:d=1 hl=2 l= 13 cons: SEQUENCE 417:d=2 hl=2 l= 9 prim: OBJECT :md5WithRSAEncryption 428:d=2 hl=2 l= 0 prim: NULL 430:d=1 hl=4 l= 257 prim: BIT STRING
