Expand description

The sequence TBSCertificate contains information associated with the subject of the certificate and the CA that issued it.

RFC5280 definition:

  TBSCertificate  ::=  SEQUENCE  {
       version         [0]  EXPLICIT Version DEFAULT v1,
       serialNumber         CertificateSerialNumber,

Implementations

Get the version of the encoded certificate

Get the certificate subject.

Get the certificate issuer.

Get the certificate validity.

Get the certificate public key information.

Returns the certificate extensions

Returns an iterator over the certificate extensions

Searches for an extension with the given Oid.

Return Ok(Some(extension)) if exactly one was found, Ok(None) if none was found, or an error DuplicateExtensions if the extension is present twice or more.

👎 Deprecated since 0.13.0:

Do not use this function (duplicate extensions are not checked), use get_extension_unique

Searches for an extension with the given Oid.

Duplicate extensions

Note: if there are several extensions with the same Oid, the first one is returned, masking other values.

RFC5280 forbids having duplicate extensions, but does not specify how errors should be handled.

Because of this, the find_extension method is not safe and should not be used! The get_extension_unique method checks for duplicate extensions and should be preferred.

Builds and returns a map of extensions.

If an extension is present twice, this will fail and return DuplicateExtensions.

Attempt to get the certificate Basic Constraints extension

Return Ok(Some(extension)) if exactly one was found, Ok(None) if none was found, or an error if the extension is present twice or more.

Attempt to get the certificate Key Usage extension

Return Ok(Some(extension)) if exactly one was found, Ok(None) if none was found, or an error if the extension is invalid, or is present twice or more.

Attempt to get the certificate Extended Key Usage extension

Return Ok(Some(extension)) if exactly one was found, Ok(None) if none was found, or an error if the extension is invalid, or is present twice or more.

Attempt to get the certificate Policy Constraints extension

Return Ok(Some(extension)) if exactly one was found, Ok(None) if none was found, or an error if the extension is invalid, or is present twice or more.

Attempt to get the certificate Policy Constraints extension

Return Ok(Some(extension)) if exactly one was found, Ok(None) if none was found, or an error if the extension is invalid, or is present twice or more.

Attempt to get the certificate Policy Mappings extension

Return Ok(Some(extension)) if exactly one was found, Ok(None) if none was found, or an error if the extension is invalid, or is present twice or more.

Attempt to get the certificate Subject Alternative Name extension

Return Ok(Some(extension)) if exactly one was found, Ok(None) if none was found, or an error if the extension is invalid, or is present twice or more.

Attempt to get the certificate Name Constraints extension

Return Ok(Some(extension)) if exactly one was found, Ok(None) if none was found, or an error if the extension is invalid, or is present twice or more.

Returns true if certificate has basicConstraints CA:true

Get the raw bytes of the certificate serial number

Get a formatted string of the certificate serial number, separated by ‘:’
