KeyData

Represents a public key data along with its format.

JSON representation
{"format":enum (`KeyFormat`),"notBeforeTime":string,"notAfterTime":string,"key":string,"keySpec":enum (`KeySpec`)}

Fields
`format`	`enum (KeyFormat)` Output only. The format of the key.
`notBeforeTime`	`string (Timestamp format)` Output only. Earliest timestamp when this key is valid. Attempts to use this key before this time will fail. Only present if the key data represents a X.509 certificate. Uses RFC 3339, where generated output will always be Z-normalized and use 0, 3, 6 or 9 fractional digits. Offsets other than "Z" are also accepted. Examples:`"2014-10-02T15:01:23Z"`,`"2014-10-02T15:01:23.045123456Z"` or`"2014-10-02T15:01:23+05:30"`.
`notAfterTime`	`string (Timestamp format)` Output only. Latest timestamp when this key is valid. Attempts to use this key after this time will fail. Only present if the key data represents a X.509 certificate. Uses RFC 3339, where generated output will always be Z-normalized and use 0, 3, 6 or 9 fractional digits. Offsets other than "Z" are also accepted. Examples:`"2014-10-02T15:01:23Z"`,`"2014-10-02T15:01:23.045123456Z"` or`"2014-10-02T15:01:23+05:30"`.
`key`	`string` Output only. The key data. The format of the key is represented by the`format` field.
`keySpec`	`enum (KeySpec)` Required. The specifications for the key.
