Queries X and Y of public key.
Example 
// make a key
Const NID_secp192k1 = 711
Dim e As ECKeyMBS = ECKeyMBS.KeyByCurveName(NID_secp192k1)

// show public key
dim x,y as string
If e.GetPublicKey(x, y, False) Then
  MsgBox x+EndOfLine+y
End If

The public key is made up with two big numbers, which can be returned as decimal or hexadecimal value.
Returns true on success or false on failure.

// make a key
Const NID_secp192k1 = 711
Dim e As ECKeyMBS = ECKeyMBS.KeyByCurveName(NID_secp192k1)

// show public key
msgbox e.GetPublicKeyPoint

Can be queried to save/send and later be assigned with SetPublicKeyPoint.

ECKeyMBS.PrivateKey as String

Type Topic Plugin Version macOS Windows Linux iOS Targets

Queries the priv key.
Example 
const NID_secp192k1 = 711
dim key as ECKeyMBS = ECKeyMBS.KeyByCurveName(NID_secp192k1)
dim Data as string = key.PrivateKey
MsgBox EncodeBase64(data)

ECKeyMBS.PublicKey as String

Queries the public key.
Example 
const NID_secp192k1 = 711
dim key as ECKeyMBS = ECKeyMBS.KeyByCurveName(NID_secp192k1)
dim Data as string = key.PublicKey
MsgBox EncodeBase64(data)

ECKeyMBS.SetPrivateKey(Value as String, Hex as Boolean) as Boolean

Type Topic Plugin Version macOS Windows Linux iOS Targets
method Encryption and Hash MBS Encryption Plugin 20.2 ✅ Yes ✅ Yes ✅ Yes ✅ Yes All
Sets the key.
Example 
// make a key
Const NID_secp192k1 = 711
Dim e As ECKeyMBS = ECKeyMBS.KeyByCurveName(NID_secp192k1)

MsgBox e.Description

// get hex
Dim pubk As String = e.GetPublicKeyPoint
Dim priv As String = e.GetPrivateKey(False)


// make new empty key and put in the data
Dim ee As ECKeyMBS = ECKeyMBS.KeyByCurveName(NID_secp192k1, False)

If ee.SetPrivateKey(priv, False) Then
  If ee.SetPublicKeyPoint(pubk) Then
    MsgBox ee.Description
  Else
    Break // failed?
  End If
Else
  Break // failed?
End If

Returns true on success or false on failure.

ECKeyMBS.SetPublicKey(x as String, y as String, Hex as Boolean) as Boolean

Type Topic Plugin Version macOS Windows Linux iOS Targets
method Encryption and Hash MBS Encryption Plugin 20.2 ✅ Yes ✅ Yes ✅ Yes ✅ Yes All
Sets X and Y of public key.
Example 
// make a key
Const NID_secp192k1 = 711
Dim e As ECKeyMBS = ECKeyMBS.KeyByCurveName(NID_secp192k1)

MsgBox e.Description

// get hex
Dim pubk As String = e.GetPublicKeyPoint
Dim priv As String = e.GetPrivateKey(False)


// make new empty key and put in the data
Dim ee As ECKeyMBS = ECKeyMBS.KeyByCurveName(NID_secp192k1, False)

If ee.SetPrivateKey(priv, False) Then
  If ee.SetPublicKeyPoint(pubk) Then
    MsgBox ee.Description
  Else
    Break // failed?
  End If
Else
  Break // failed?
End If

Returns true on success or false on failure.

ECKeyMBS.SetPublicKeyPoint(Value as String) as Boolean

Type Topic Plugin Version macOS Windows Linux iOS Targets
method Encryption and Hash MBS Encryption Plugin 20.2 ✅ Yes ✅ Yes ✅ Yes ✅ Yes All
Sets public key.

Returns true on success or false on failure.

ECKeyMBS.Sign(Data as String) as String

Type Topic Plugin Version macOS Windows Linux iOS Targets
method Encryption and Hash MBS Encryption Plugin 15.4 ✅ Yes ✅ Yes ✅ Yes ✅ Yes All
Signs the given data.
Example 
const NID_secp192k1 = 711
dim key as ECKeyMBS = ECKeyMBS.KeyByCurveName(NID_secp192k1)
dim text as string = "Hello World"
dim data as string = SHA512MBS.Hash(text)
dim sig as string = key.Sign(data)

if key.Verify(data, sig) then
  MsgBox "Signature ok"
end if

We highly recommend to use a hash like SHA-512 to preprocess the data.
Returns the signature as string on success.

ECKeyMBS.Verify(SignatureData as String, Data as String) as Boolean

Type Topic Plugin Version macOS Windows Linux iOS Targets
method Encryption and Hash MBS Encryption Plugin 15.4 ✅ Yes ✅ Yes ✅ Yes ✅ Yes All
Verifies the digital signature.
Example 
const NID_secp192k1 = 711
dim key as ECKeyMBS = ECKeyMBS.KeyByCurveName(NID_secp192k1)
dim text as string = "Hello World"
dim data as string = SHA512MBS.Hash(text)
dim sig as string = key.Sign(data)

if key.Verify(data, sig) then
  MsgBox "Signature ok"
end if

Returns true on success. Returns false if data, signature and public key don't belong together.
We highly recommend to use a hash like SHA-512 to preprocess the data.
