Sign()
Returns the signature bytes of all the data updated.
[Android.Runtime.Register("sign", "()[B", "")]
public byte[]? Sign ();[<Android.Runtime.Register("sign", "()[B", "")>]
member this.Sign : unit -> byte[]Returns
the signature bytes of the signing operation's result.
- Attributes
Exceptions
if this Signature instance is not initialized
properly.
Remarks
Returns the signature bytes of all the data updated. The format of the signature depends on the underlying signature scheme.
A call to this method resets this signature object to the state it was in when previously initialized for signing via a call to initSign(PrivateKey). That is, the object is reset and available to generate another signature from the same signer, if desired, via new calls to update and sign.

Applies to
Sign(Byte[], Int32, Int32)
Finishes the signature operation and stores the resulting signature
bytes in the provided buffer outbuf, starting at
offset.
[Android.Runtime.Register("sign", "([BII)I", "")]
public int Sign (byte[]? outbuf, int offset, int len);[<Android.Runtime.Register("sign", "([BII)I", "")>]
member this.Sign : byte[] * int * int -> intParameters
- outbuf
- Byte[]
buffer for the signature result.
- offset
- Int32
offset into outbuf where the signature is
stored.
- len
- Int32
number of bytes within outbuf allotted for the
signature.
Returns
the number of bytes placed into outbuf.
- Attributes
Exceptions
if this Signature instance is not initialized
properly.
if offset or len are not valid in respect to
outbuf.
Remarks
Finishes the signature operation and stores the resulting signature bytes in the provided buffer outbuf, starting at offset. The format of the signature depends on the underlying signature scheme.
This signature object is reset to its initial state (the state it was in after a call to one of the initSign methods) and can be reused to generate further signatures with the same private key.
