V$RMAN_ENCRYPTION_ALGORITHMS displays supported encryption algorithms. It is used by the RMAN client to validate user-requested algorithms. This view will list AES128, AES192, and AES256 encryption algorithms for the current release. The default algorithm is AES128.

Column Datatype Description
ALGORITHM_ID NUMBER Number to identify the algorithm
ALGORITHM_NAME VARCHAR2(64) Name of the algorithm (for example, AES128, AES192, or AES256)
ALGORITHM_DESCRIPTION VARCHAR2(64) Description of the algorithm
IS_DEFAULT VARCHAR2(3) Indicates whether this is the default encryption algorithm (YES) or not (NO). This value is set by Oracle Database and may vary for each Release (that is, it is not dependent on user-specified RMAN configuration).
RESTORE_ONLY VARCHAR2(3) Indicates whether this algorithm can be used for restore only (YES) or not (NO). If the value is NO, then the algorithm is also allowed for backup. This column is useful in determining whether an encryption algorithm is deprecated for backup purpose.
