Appendix C: IBMJCE Keysize Restrictions
The IBMJCE provider enforces the following restrictions on the keysize passed to the initialization methods of the following classes:
- KeyGenerator
- Restrictions (by algorithm):
- DES: keysize must be equal to
56 - Triple DES: keysize must be equal to
112or168Note: A keysize of112will generate a Triple DES key with 2 intermediate keys, and a keysize of168will generate a Triple DES key with 3 intermediate keys. - Blowfish: keysize must be a multiple of
8, and can only range from32to448, inclusive
- DES: keysize must be equal to
- KeyPairGenerator
- Restrictions (by algorithm):
- Diffie-Hellman: keysize must be a multiple of
64, and can only range from512to2048, inclusive
- Diffie-Hellman: keysize must be a multiple of
- AlgorithmParameterGenerator
- Restrictions (by algorithm):
- Diffie-Hellman: keysize must be a multiple of
64, and can only range from512to2048, inclusive
- Diffie-Hellman: keysize must be a multiple of
