+## crypto.js browser edition, which provides regular using
+
+[中文 Readme](./Readme.md)
+
+Thanks these two libraries:
+
+1. [spark-md5](https://github.com/satazor/js-spark-md5), After some testing, this is indeed the highest performing version in the pure JS version. It has been introduced into this warehouse and adjusted to be used in ESM mode.
+2. [base64](https://github.com/beatgammit/base64-js), Fully supported base64 library, which supports encoding Chinese characters compared to the native btoa() method.
+
+
+These two libraries are included in index.js. If you have specific requirements on size, you can use them separately.
+
+
+```js
+// all in one
+import { sha1, hmac, md5, base64encode } from '//unpkg.com/crypto.web.js/dist/index.js'
+
+// md5
+import { md5, md5Sum } from '//unpkg.com/crypto.web.js/latest/md5.js'
+
+// base64
+import { base64encode, base64decode } from '//unpkg.com/crypto.web.js/latest/base64.js'
+
+import { sha1, hmac } from '//unpkg.com/crypto.web.js/latest/crypto.js'
+
+```
+
+### APIs
+
+#### 1. md5(str`<String>|<Number>`) 
+> regular md5 function, you can use to calculate a small string(<100MB). 
+
+
+#### 2. md5Sum(ab`<ArrayBuffer>`) 
+> you can use this to calculate a large data. Need an `ArrayBuffer` object which can get the value through `FileReader` , and the `Blob` object of the new browser also has an `arraybuffer` prototype method。
+
+
+#### 3. base64encode(str`<String>`) 
+> Base64 encoding, supports Chinese.
+
+
+#### 4. base64decode(str`<String>`) 
+> Base64 decoding.
+
+
+#### 5. uuid() 
+> Generate a unique 24-bit random string. Only guarantees uniqueness on a single machine.
+
+
+#### 6. ab2hex(ab`<ArrayBuffer>`) 
+> Convert an `arraybuffer` object to a hexadecimal string.
+
+
+#### 7. ab2bin(ab`<ArrayBuffer>`) 
+> Convert an `arraybuffer` object to a Binary string.
+
+
+#### 8. sha1(str`<String>`) 
+> Calculate the `sha1` value of the specified string.
+>> Note: The return value of this method is not a string, but a `Promise` object.
+
+
+#### 9. sha256(str`<String>`) 
+> Calculate the `sha256` value of the specified string.
+>> Note: The return value of this method is not a string, but a `Promise` object.
+
+
+#### 10. sha512(str`<String>`) 
+> Calculate the `sha512` value of the specified string.
+>> Note: The return value of this method is not a string, but a `Promise` object.
+
+
+#### 11. hash(algorithm`<String>`, data`<String>|<ArrayBuffer>|<Uint8Array>`) 
+> Hash algorithm, used to implement fuzzy processing of some important data, to achieve the purpose of hiding plaintext. The above sha1, sha256, etc., are actually based on this re-encapsulation result; algorithm, optional values ​​are: SHA-1, SHA-256, SHA-384, SHA-512.
+>> Note: The return value of this method is not a string, but a Promise object.
+
+
+#### 12. hmac(algorithm`<String>`, data`<String>|<ArrayBuffer>|<Uint8Array>`, key`<String>|<Uint8Array>`, outEncode`<String>`) 
+> HMAC algorithm, which is a combination of a hash algorithm and a key to prevent the destruction of signature integrity. Compared with the above hash algorithm, it has an additional key parameter.
+>> Note: The return value of this method is not a string, but a Promise object.
