java.lang.Object
net.i2p.router.transport.udp.I2PHMac
class I2PHMac extends Object
HMAC implementation based on RFC2104
H(K XOR opad, H(K XOR ipad, text))
modified by jrandom to use the session key byte array directly and to cache
a frequently used buffer (called on doFinal). changes released into the public
domain in 2005.
This is renamed from HMac because the constructor HMac(digest, sz) does not exist
in the standard bouncycastle library, thus it conflicts in JVMs that contain the
standard library (Android).
As of 0.9.12, refactored to use standard MessageDigest.
Deprecated - Do not use outside of router or Syndie.
Not a public API - Not for external use!
- Since:
- 0.9.43 moved from org.bouncycastle.oldcrypto.macs
