Enum Usage 

pub enum Usage {
    certsign,
    crlsign,
    encipherment,
    clientauth,
    serverauth,
    signature,
    contentcommitment,
}

Represents the allowed usages for a certificate, used in KeyUsage and ExtendedKeyUsage extensions.

Variants

certsign

Allows the certificate to sign other certificates (typically used for CA certificates).

crlsign

Allows the certificate to sign certificate revocation lists (CRLs).

encipherment

Allows the certificate to be used for encrypting data (e.g., key encipherment).

clientauth

Indicates the certificate can be used for client authentication in TLS.

serverauth

Indicates the certificate can be used for server authentication in TLS.

signature

Allows the certificate to be used for digital signatures.

contentcommitment

Indicates the certificate can be used for content commitment (non-repudiation).
