今天在使用easywechat对接企业打款到银行卡时，遇到了两个错误
error:0906D064:PEM routines:PEM_read_bio:bad base64 decodeerror:0906D06C:PEM routines:PEM_read_bio:no start line
这是因为想要正确的使用密钥，需要满足以下三个条件。
- error:0906D06C:PEM routines:PEM_read_bio:no start line
- error:0906D06C:PEM routines:PEM_read_bio:no start line
- 以上2步应该可以满足有些语言的需求，但php不行，还需要讲以上PKCS#1 格式密钥转换成PKCS#8 格式密钥。
下面看下具体操作。按照文档使用如下命令：
./vendor/bin/easywechat payment:rsa_public_key \ --mch_id=14339221228 \ --api_key=36YTbDmLgyQ52noqdxgwGiYy \ --cert_path=/Users/overtrue/www/demo/apiclient_cert.pem \ --key_path=/Users/overtrue/www/demo/apiclient_key.pem
./public-14339221228.pem
如果直接使用这个public key文件，会报一个非法的key错误，然后可以发现easywechat有这样一段源码。
function rsa_public_encrypt($content, $publicKey) { $encrypted = ''; openssl_public_encrypt($content, $encrypted, openssl_pkey_get_public($publicKey), OPENSSL_PKCS1_OAEP_PADDING); return base64_encode($encrypted); } openssl_pkey_get_public($publicKey)
function rsa_public_encrypt($content, $publicKey) { $encrypted = ''; openssl_public_encrypt($content, $encrypted, openssl_pkey_get_public($publicKey), OPENSSL_PKCS1_OAEP_PADDING); var_dump(openssl_error_string()); return base64_encode($encrypted); } 这是会看到以下错误。
