The `-v2` option for `pkcs8` existed back in the year 2000, when OpenSSL 0.9.5a was released: [OpenSSL doc page for pkcs8 from Archive.org](https://web.archive.org/web/20001020093418/http://www.openssl.org/docs/apps/pkcs8.html). Hopefully you're not using a version older than that. If so, good luck finding an earlier reference. – leeharvey1 Sep 01 '22 at 16:53

Further research looks like the `-v2` option of `pkcs8` was introduced in OpenSSL 0.9.4, August of 1999. – leeharvey1 Sep 01 '22 at 17:01
