<ul dir="auto" style="text-align: initial; list-style-type: disc; margin: 0 0 16px; padding: 0;">
<li style="margin-top: 0; line-height: 1.6em; margin-left: 25px; padding-left: 3px;">Modify <code style='font-size: 90%; color: #1f1e24; word-wrap: break-word; background-color: #ececef; border-radius: 4px; margin-top: 0; font-family: var(--default-mono-font, "GitLab Mono"),"JetBrains Mono","Menlo","DejaVu Sans Mono","Liberation Mono","Consolas","Ubuntu Mono","Courier New","andale mono","lucida console",monospace; white-space: pre-wrap; overflow-wrap: break-word; word-break: keep-all; padding: 2px 4px;'>lib/pkix.asn</code> to include the publicKey field, with RFC 5958 as a reference</li>
<li style="line-height: 1.6em; margin-left: 25px; padding-left: 3px;">Encoding: Modify <code style='font-size: 90%; color: #1f1e24; word-wrap: break-word; background-color: #ececef; border-radius: 4px; margin-top: 0; font-family: var(--default-mono-font, "GitLab Mono"),"JetBrains Mono","Menlo","DejaVu Sans Mono","Liberation Mono","Consolas","Ubuntu Mono","Courier New","andale mono","lucida console",monospace; white-space: pre-wrap; overflow-wrap: break-word; word-break: keep-all; padding: 2px 4px;'>encode_to_private_key_info</code> as mentioned before, and add a function <code style='font-size: 90%; color: #1f1e24; word-wrap: break-word; background-color: #ececef; border-radius: 4px; font-family: var(--default-mono-font, "GitLab Mono"),"JetBrains Mono","Menlo","DejaVu Sans Mono","Liberation Mono","Consolas","Ubuntu Mono","Courier New","andale mono","lucida console",monospace; white-space: pre-wrap; overflow-wrap: break-word; word-break: keep-all; padding: 2px 4px;'>gnutls_x509_privkey_export_pkcs8v2</code> (exposing it to the public API) with the same parameters as gnutls_x509_privkey_export_pkcs8, and an additional public_key datum, which may be set to NULL.</li>
<li style="line-height: 1.6em; margin-left: 25px; padding-left: 3px;">Decoding: Modify <code style='font-size: 90%; color: #1f1e24; word-wrap: break-word; background-color: #ececef; border-radius: 4px; margin-top: 0; font-family: var(--default-mono-font, "GitLab Mono"),"JetBrains Mono","Menlo","DejaVu Sans Mono","Liberation Mono","Consolas","Ubuntu Mono","Courier New","andale mono","lucida console",monospace; white-space: pre-wrap; overflow-wrap: break-word; word-break: keep-all; padding: 2px 4px;'>_decode_pkcs8_dsa_key</code> in <code style='font-size: 90%; color: #1f1e24; word-wrap: break-word; background-color: #ececef; border-radius: 4px; font-family: var(--default-mono-font, "GitLab Mono"),"JetBrains Mono","Menlo","DejaVu Sans Mono","Liberation Mono","Consolas","Ubuntu Mono","Courier New","andale mono","lucida console",monospace; white-space: pre-wrap; overflow-wrap: break-word; word-break: keep-all; padding: 2px 4px;'>/lib/x509/privkey_pkcs8.c</code> to read the "publicKey" field if it exists.</li>
</ul>
<p dir="auto" style="color: #333238; margin: 0;" align="initial">Are these changes fine? Also, I didn't quite understand where the public key would be stored in the gnutls_x509_privkey_t data structure if they would be stored at all. Additionally, the decode functions for other algorithms could be changed, to retrieve the public key from the publicKey field if it exists, instead of computing it (as in the case of edDSA and ed25519). So can I modify those as well?</p>
