GenExemptionBlob()
Generates the exemption mechanism key blob.
[Android.Runtime.Register("genExemptionBlob", "()[B", "")]
public byte[]? GenExemptionBlob ();[<Android.Runtime.Register("genExemptionBlob", "()[B", "")>]
member this.GenExemptionBlob : unit -> byte[]Returns
the new buffer with the result key blob.
- Attributes
Exceptions
if this ExemptionMechanism instance is not
initialized.
if error(s) occur during generation.

Applies to
GenExemptionBlob(Byte[])
Generates the exemption mechanism key blob, and stores the result in
the output buffer.
[Android.Runtime.Register("genExemptionBlob", "([B)I", "")]
public int GenExemptionBlob (byte[]? output);[<Android.Runtime.Register("genExemptionBlob", "([B)I", "")>]
member this.GenExemptionBlob : byte[] -> intParameters
- output
- Byte[]
the buffer for the result
Returns
the number of bytes stored in output
- Attributes
Exceptions
if this ExemptionMechanism instance is not
initialized.
if the provided buffer is too small for the result key blob.
if error(s) occur during generation.
Remarks
Generates the exemption mechanism key blob, and stores the result in the output buffer.
If the output buffer is too small to hold the result, a ShortBufferException is thrown. In this case, repeat this call with a larger output buffer. Use #getOutputSize(int) getOutputSize to determine how big the output buffer should be.

Applies to
GenExemptionBlob(Byte[], Int32)
Generates the exemption mechanism key blob, and stores the result in
the output buffer, starting at outputOffset
inclusive.

member this.GenExemptionBlob : byte[] * int -> intParameters
- output
- Byte[]
the buffer for the result
- outputOffset
- Int32
the offset in output where the result
is stored
Returns
the number of bytes stored in output
