org.bouncycastle.crypto.generators.BCrypt.generate(byte[], byte[], int) as a direct replacement use BCrypt.generate(byte[], byte[], int, boolean) so the terminator choice is explicit at the call site — pass true to have the spec-required 0x00 terminator appended (equivalent to feeding pwInput through BCrypt.passwordToByteArray(char[])), false when the supplied bytes already include it. For general password hashing prefer OpenBSDBCrypt, which handles termination, salt formatting and the modular crypt output line; this raw primitive remains available for test-vector validation and interop with implementations that emit the 24-byte hash directly (issue #1741).
