在Node中复制“openssl sha1”

如何在纯Node中复制openssl sha1的功能？我已经尝试了下面的代码，但是当我运行它时得到的结果与当我运行openssl sha1时得到的结果不同

const crypto = require('crypto');
const key = `-----BEGIN PUBLIC KEY-----

-----END PUBLIC KEY-----`;

const sha1 = (str) => crypto.createHash('sha1').update(str).digest('hex');

pem.promisified.getPublicKey(key).then(({publicKey}) => {
  // Remove BEGIN and END blocks, newlines
  const stripped = publicKey.replace(/-----BEGIN.+KEY-----/, '').replace(/-----END.+KEY-----/,'').replaceAll('\n','');
  // Remove BEGIN and END blocks only
  const stripped2 = publicKey.replace(/-----BEGIN.+KEY-----/, '').replace(/-----END.+KEY-----/,'');
  // Remove newlines only
  const stripped3 = publicKey.replaceAll('\n','');

  console.debug("SHA1: ", sha1(publicKey));
  console.debug("SHA1 (stripped): ", sha1(stripped));
  console.debug("SHA1 (stripped2): ", sha1(stripped2));
  console.debug("SHA1 (stripped3): ", sha1(stripped3));
});

该输出：

SHA1:  2f9ab4bb70dafe6e41e401977fabea42da4c0161
SHA1 (stripped):  7cf7d0322f96221d2075123b86c5095885d5025a
SHA1 (stripped2):  58a3c4ca8e5bd33b2d2b72ea6c5bff477b743c45
SHA1 (stripped3):  f80da8adcb7362fd7bd290fa6023f4b7d35a8757

通过比较，openssl sha1计算64166b841bbb61c3f0dd7cefebb62bd79debce66的摘要。如何在不调用openssl二进制文件的情况下获得此SHA1？

H/T：dave_thompson_085，因为它弄清楚了这是沿着的换行符。
问题是我的公钥没有尾随换行符。更新的草图（减去所有剥离）：

const pem = require('pem');
const crypto = require('crypto');

const key = `-----BEGIN PRIVATE KEY-----

const sha1 = (str) => crypto.createHash('sha1').update(str).digest('hex');

pem.promisified.getPublicKey(key).then(({publicKey}) => {
  // getPublicKey doesn't append a newline
  publicKey = publicKey + '\n';
  console.debug({publicKey});
  console.debug("SHA1: ", sha1(publicKey));
