(decrypt {:keys [cipher-kit salt-size salt->key-fn ba]
          :or {cipher-kit cipher-kit-aes-gcm}})

encrypt clj

(encrypt {:keys [cipher-kit ?salt-ba key-ba ba rand-bytes-fn]
          :or {cipher-kit cipher-kit-aes-gcm rand-bytes-fn rand-bytes}})

gcm-cipher clj

(gcm-cipher)

ICipherKit clj protocol

Returns a thread-safe javax.crypto.Cipher instance.

get-iv-size clj

(get-iv-size _)

Returns necessary iv-ba length.

get-key-spec clj

(get-key-spec _ ba)

Returns a javax.crypto.spec.SecretKeySpec.

get-param-spec clj

(get-param-spec _ iv-ba)

Returns a java.security.spec.AlgorithmParameters.

murmur3 clj

(murmur3 s)

prng clj

(prng)

Favours security over performance. May block while waiting on system entropy!

rand-bool clj

(rand-bool)

Uses prng

rand-bytes clj

(rand-bytes size)

Uses prng

rand-double clj

(rand-double)

Uses prng

rand-gauss clj

(rand-gauss)

Uses prng

rand-long clj

(rand-long)

Uses prng

sha256-ba clj

(sha256-ba ba)

sha256-md clj

(sha256-md)

sha512-ba clj

(sha512-ba ba)

sha512-key-ba clj

(sha512-key-ba ?salt-ba utf8)

(sha512-key-ba ?salt-ba utf8 n-rounds)

SHA512-based key generator. Good JVM availability without extra dependencies (PBKDF2, bcrypt, scrypt, etc.). Decent security when using many rounds.
