GetInstance(String)
Returns a Cipher object that implements the specified
transformation.
[Android.Runtime.Register("getInstance", "(Ljava/lang/String;)Ljavax/crypto/Cipher;", "")]
public static Javax.Crypto.Cipher? GetInstance (string? transformation);[<Android.Runtime.Register("getInstance", "(Ljava/lang/String;)Ljavax/crypto/Cipher;", "")>]
static member GetInstance : string -> Javax.Crypto.CipherParameters
- transformation
- String
the name of the transformation, e.g., DES/CBC/PKCS5Padding. See the Cipher section in the Java Cryptography Architecture Standard Algorithm Name Documentation for information about standard transformation names.
Returns
a cipher that implements the requested transformation.
- Attributes
Exceptions
if no installed provider can provide the
transformation, or it is null, empty or in an
invalid format.
if no installed provider can provide the padding scheme in the transformation.
Remarks
Returns a Cipher object that implements the specified transformation.
This method traverses the list of registered security Providers, starting with the most preferred Provider. A new Cipher object encapsulating the CipherSpi implementation from the first Provider that supports the specified algorithm is returned.
Note that the list of registered providers may be retrieved via the Security#getProviders() Security.getProviders() method.

- transformation
- String
the name of the transformation, e.g., DES/CBC/PKCS5Padding. See the Cipher section in the Java Cryptography Architecture Standard Algorithm Name Documentation for information about standard transformation names.
- provider
- Provider
the provider.
Returns
a cipher that implements the requested transformation.
- Attributes
Exceptions
if the specified provider can not provide the
transformation, or it is null, empty or in an
invalid format.
if the requested padding scheme in the transformation is not available.
if the provider is null.
Remarks
Returns a Cipher object that implements the specified transformation.
A new Cipher object encapsulating the CipherSpi implementation from the specified Provider object is returned. Note that the specified Provider object does not have to be registered in the provider list.
