Hopefully can work it out

Can you provide a minimal code example?

Can you provide a minimal code example?

The SIGN I returned with JavaWeb does not contain Chinese and can be passed angular: Returns false after using Chinese

[a1031101978]

Can you provide a minimal code example?

This is what happens when use Chinese 中文

[a1031101978]

Also in?

@a1031101978,

Please take a look at these issues: https://github.com/digitalbazaar/forge/issues?q=chinese

You need to convert your character strings into binary-encoded strings (so each character uses a character code of 0-255, i.e. a "string of bytes") when using forge. This is because forge was written before Uint8Array existed. Therefore, use the UTF-8 encoding APIs to convert a string of characters into a string of bytes before passing the string to the various crypto APIs.

@a1031101978 As @dlongley said,you should encode those Chinese characters to utf-8 style first. for encryption

    const publickeyStr = "<public key...>";
    const plaintextStr = "我爱你";
    const publickey = forge.pki.publicKeyFromPem(publickeyStr);
    const buffer = forge.util.createBuffer();
    buffer.data = forge.util.encodeUtf8(plaintextStr)
    const encryptedStr = forge.util.encode64(publickey.encrypt(buffer.bytes()))
    console.log(encryptedStr);

for decryption

    const privatekeyStr = "<private key...>"
    const encryptedStr = "<encrypted string ...>";
    const privateKey = forge.pki.privateKeyFromPem(privatekeyStr);
    const decrypted = privateKey.decrypt(forge.util.decode64(encryptedStr))
    const plaintextStr = forge.util.decodeUtf8(decrypted)
    console.log(plaintextStr);

I think this issue should be closed.

Thanks! I agree -- closing.
