SecretKeySpec(Byte[], String)
Constructs a secret key from the given byte array.

public SecretKeySpec (byte[]? key, string? algorithm);[<Android.Runtime.Register(".ctor", "([BLjava/lang/String;)V", "")>]

- key
- Byte[]
the key material of the secret key. The contents of the array are copied to protect against subsequent modification.
- algorithm
- String
the name of the secret-key algorithm to be associated with the given key material. See Appendix A in the Java Cryptography Architecture Reference Guide for information about standard algorithm names.
- Attributes
Exceptions
if the key data or the algorithm name is null or if the key data is empty.
Remarks
Constructs a secret key from the given byte array.
This constructor does not check if the given bytes indeed specify a secret key of the specified algorithm. For example, if the algorithm is DES, this constructor does not check if key is 8 bytes long, and also does not check for weak or semi-weak keys. In order for those checks to be performed, an algorithm-specific key specification class (in this case: DESKeySpec DESKeySpec) should be used.

SecretKeySpec(Byte[], Int32, Int32, String)
Constructs a secret key from the given byte array, using the first
len bytes of key, starting at
offset inclusive.
[Android.Runtime.Register(".ctor", "([BIILjava/lang/String;)V", "")]
public SecretKeySpec (byte[]? key, int offset, int len, string? algorithm);[<Android.Runtime.Register(".ctor", "([BIILjava/lang/String;)V", "")>]
new Javax.Crypto.Spec.SecretKeySpec : byte[] * int * int * string -> Javax.Crypto.Spec.SecretKeySpecParameters
- key
- Byte[]
the key material of the secret key. The first
len bytes of the array beginning at
offset inclusive are copied to protect
against subsequent modification.
- offset
- Int32
the offset in key where the key material
starts.
- len
- Int32
the length of the key material.
- algorithm
- String
the name of the secret-key algorithm to be associated with the given key material. See Appendix A in the Java Cryptography Architecture Reference Guide for information about standard algorithm names.
- Attributes
Exceptions
if the key data or the algorithm name is null, the key data
is empty or offset and len do not
specify a valid chunk in the buffer key.
if offset or len is negative.
Remarks
Constructs a secret key from the given byte array, using the first len bytes of key, starting at offset inclusive.
The bytes that constitute the secret key are those between key[offset] and key[offset+len-1] inclusive.
This constructor does not check if the given bytes indeed specify a secret key of the specified algorithm.
