我正在尝试使用AWS Lambda在Swift中验证使用sec256r1创建的签名。
消息:"some text to sign"
也已使用SHA256进行哈希处理
签名将以base64格式呈现
encoding:MEYCIQCPfWhpzxMqu3gZWflBm5V0aetgb2/S+SGyGcElaOjgdgIhALaD4lbxVwa8HUUBFOLz+CGvIioDkf9oihSnXHCqh8yV
公钥将会长成这样:
-----BEGIN PUBLIC KEY-----
MFkwEwYHKoZIzj0CAQYIKoZIzj0DAQcDQgAEXIvPbzLjaPLd8jgiv1TL/X8PXpJN
gDkGRj9U9Lcx1yKURpQFVavcMkfWyO8r7JlZNMax0JKfLZUM1IePRjHlFw==
-----END PUBLIC KEY-----
为了澄清,我正在尝试使用lambda来验证来自客户端的签名,并在需要时使用其公钥加密数据。
以下是代码:
const crypto = require('crypto');
const verify = crypto.createVerify('SHA256');
verify.write('some text to sign');
verify.end();
const l1 = "-----BEGIN PUBLIC KEY-----\n"
const l2 =
"MFkwEwYHKoZIzj0CAQYIKoZIzj0DAQcDQgAEXIvPbzLjaPLd8jgiv1TL/X8PXpJNgDkGRj9U9Lcx1yKURpQFVavcMkfWyO8r7JlZNMax0JKfLZUM1IePRjHlFw=="
const l3 = "\n-----END PUBLIC KEY-----"
const publicKey = l1 + l2 + l3
const signature = "MEYCIQCPfWhpzxMqu3gZWflBm5V0aetgb2/S+SGyGcElaOjgdgIhALaD4lbxVwa8HUUBFOLz+CGvIioDkf9oihSnXHCqh8yV";
console.log(verify.verify(publicKey, signature));// Prints: true or false
