aes128GcmSivTemplate

public static final KeyTemplate aes128GcmSivTemplate()

Creates and returns a KeyTemplate that generates new instances of AES-GCM-SIV with the following parameters:

• Key size: 16 bytes
• Prefix type: KeyTemplate.OutputPrefixType.TINK

rawAes128GcmSivTemplate

public static final KeyTemplate rawAes128GcmSivTemplate()

Creates and returns a KeyTemplate that generates new instances of AES-GCM with the following parameters:

• Key size: 16 bytes
