getEncryptionAlg
public EncryptionAlgorithm getEncryptionAlg()
- Returns the EncryptionAlgorithm that should be used with keys
generated with this PBEAlgorithm. For example,
PBE_MD2_DES_CBC.getEncryptionAlg()
returns
EncryptionAlgorithm.DES_CBC
.
getSaltLength
public int getSaltLength()
- Returns the number of bytes of salt that should be supplied when
generating keys with this algorithm.
PKCS #5 algorithms require exactly 8 bytes of salt. PKCS #12
algorithms take
a variable length, but recommend that the salt length be at least
as long as the output of the hash function. For SHA-1, the output
length is 20 bytes.
