@cool-firer Can you submit the original xls file and the encrypted file?
Let's check here.

Sure, files as below, and the code is like this:

//
const fs = require("fs");
const path = require("node:path");
const officeCrypto = require("officecrypto-tool");

function main() {
  const src = "./a/test1.xls";
  const input = fs.readFileSync(src);
  const output = officeCrypto.encrypt(input, { password: "123456" });

  const dst = "./a/test1_enc.xls";
  fs.writeFileSync(dst, output);
}

main();

test1.xls
test1_enc.xls

test1.xls test1_enc.xls

@cool-firer Understood the issue, currently only supports XLSX format encryption, not XLS encryption

[cool-firer]

ok then, any plan to support XLS encryption?

[zurmokeeper]

@cool-firer Yes, leave this issue is a reminder to do this function, but this is a little difficult, the biggest problem is not to find the encrypted document, can only rely on guessing, xls encryption is not a simple decryption of the reverse, I have spent a lot of time, but also not yet completed.
