Published Test Vectors

Favre OpenBSD BCrypt Test Vectors

Since there are no official test vectors, I created some as reference for this implementation. It may be used to check other implementation or compatibility between this implementation and others.

The format of the test data is

TestEntry(
    String plainPw, // password encoded as string
    int cost, // the log working factor (4-31)
    String radix64Salt, // the 16 byte salt encoded in the OpenBSD radix64 encoding 
    String hash // the hash in the modular crypt format: ${identifier}${cost-factor}${16-bytes-salt-radix64}{23-bytes-hash-radix64}
)

All strings are escaped for Java (e.g. " will be escaped as \" and \ as \\). You can use tools like this, to get the raw text.

Test Vectors

This is version 1 (5f89203) of the test vector suite.
