用法

# Instantiate a decrypter with your base derivation key (BDK)
decrypter = DUKPT::Decrypter.new("0123456789ABCDEFFEDCBA9876543210")

# You can specify whether you want to use "ecb" cipher mode if needed. The default is "cbc".
decrypter = DUKPT::Decrypter.new("0123456789ABCDEFFEDCBA9876543210", "ecb")
  
# Pass the ciphertext and the current Key Serial Number (KSN), as hex encoded strings, to the decryptor to get back the plaintext
ksn = "FFFF9876543210E00008"
ciphertext = "C25C1D1197D31CAA87285D59A892047426D9182EC11353C051ADD6D0F072A6CB3436560B3071FC1FD11D9F7E74886742D9BEE0CFD1EA1064C213BB55278B2F12"
  
plaintext = decrypter.decrypt(ciphertext, ksn) # => "%B5452300551227189^HOGAN/PAUL      ^08043210000000725000000?\x00\x00\x00\x00"
