IBY_SYS_SECURITY_SUBKEYS
IBY_SYS_SECURITY_SUBKEYS stores the security sub-keys used for data encryption. A sub-key is a randomly generated number used to encrypt only a fixed number of data rows, after which a new sub-key is randomly generated. The sub-key is stored as cipher-text in this table.

Name | Datatype | Length | Precision | Not-null | Comments |
---|---|---|---|---|---|
SEC_SUBKEY_ID | NUMBER | 18 | Yes | Sequence-generated primary key | |
SUBKEY_CIPHER_TEXT | RAW | 50 | Yes | Cipher text of the sub-key | |
USE_COUNT | NUMBER | 18 | Yes | Number of times the sub-key was used to encrypt data | |
CREATED_BY | VARCHAR2 | 64 | Yes | Who column: indicates the user who created the row. | |
CREATION_DATE | TIMESTAMP | Yes | Who column: indicates the date and time of the creation of the row. | ||
LAST_UPDATED_BY | VARCHAR2 | 64 | Yes | Who column: indicates the user who last updated the row. | |
LAST_UPDATE_DATE | TIMESTAMP | Yes | Who column: indicates the date and time of the last update of the row. | ||
LAST_UPDATE_LOGIN | VARCHAR2 | 32 | Who column: indicates the session login associated to the user who last updated the row. | ||
