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".
