public RC2ParameterSpec(int effectiveKeyBits)
effectiveKeyBits
- the effective key size in bits.public RC2ParameterSpec(int effectiveKeyBits, byte[] iv)
The bytes that constitute the IV are those between
iv[0]
and iv[7]
inclusive.
effectiveKeyBits
- the effective key size in bits.iv
- the buffer with the 8-byte IV. The first 8 bytes of
the buffer are copied to protect against subsequent modification.
IllegalArgumentException
- if iv
is null.public RC2ParameterSpec(int effectiveKeyBits, byte[] iv, int offset)
The IV is taken from iv
, starting at
offset
inclusive.
The bytes that constitute the IV are those between
iv[offset]
and iv[offset+7]
inclusive.
effectiveKeyBits
- the effective key size in bits.iv
- the buffer with the IV. The first 8 bytes
of the buffer beginning at offset
inclusive
are copied to protect against subsequent modification.offset
- the offset in iv
where the 8-byte IV
starts.
