WebThe official name as used by NIST is the Triple Data Encryption Algorithm (TDEA). TDEA encrypts and decrypts data using three 56-bit keys into 64-bit blocks. TDEA has two additional variations: Two-key TDEA (2TDEA) using 3 keys, however key 1 and key 3 are identical. This leads to 112 effective bits.
