Description of the problem

The page for x509.keyUsage indicates that it returns An array detailing the key usages for this certificate. while in fact it only returns the extended key usage for the certificate. For example:

• 1.3.6.1.5.5.7.3.1 for TLS Web server
• or 1.3.6.1.5.5.7.3.2 for TLS Web client

Key usages (not extend) are completely different are related to certificate extension under OID 2.5.29.15 to contain value in a bit array format.

Key usage can have for definition: Digital signature, Non-repudiation, Key encipherment, Data encipherment, Key agreement, Certificate signing, CRL signing, Encipher only, Decipher only.

Therefore the API should be x509.extKeyUsage and the definition An array detailing the key extended usages for this certificate. to match the reality of the function.
