我正在尝试使用IE11的JavaScript通过以下代码实现公钥加密:
<script>
var data = new Uint8Array([0, 1, 2, 3, 4, 5, 6, 7, 8, 9]);
var crypto = window.crypto || window.msCrypto;
var cryptoSubtle = crypto.subtle;
var genOp = cryptoSubtle.generateKey(
{
name: "RSA-OAEP",
modulusLength: 2048,
publicExponent: new Uint8Array([0x01, 0x00, 0x01]),
hash: { name: "SHA-256" },
},
true,
["encrypt", "decrypt"]
);
genOp.onerror = function (e) {
console.error(e);
};
genOp.oncomplete = function (e) {
var key = e.target.result;
console.log(key);
console.log(key.publicKey);
var encOp = cryptoSubtle.encrypt(
{
name: "RSA-OAEP"
},
key.publicKey,
data
);
encOp.onerror = function (e) {
console.error(e);
};
encOp.oncomplete = function (e) {
var encrypted = e.target.result;
console.log(new Uint8Array(encrypted));
};
};
</script>

它会生成密钥对,但无法通过错误事件进行加密。具有对称AES密钥的类似代码也可以工作。IE11支持公钥加密吗?我的代码有什么问题吗?
我已经找到了原因。调用加密调用时,我需要添加哈希字段:
var encOp = cryptoSubtle.encrypt(
{
name: "RSA-OAEP",
hash: { name: "SHA-256" }
},
key.publicKey,
data
);

这与Web密码学API规范不匹配,但是可以正常工作。
