lock-key.core — lock-key 1.5.0

Wrapper around the Java cryptography extensions in javax.crypto. Implements symmetric encryption in AES/CBC/PKCS5Padding mode.

decrypt clj

(decrypt value encryption-key)

Decrypts a value which has been encrypted via (encrypt). Returns byte[].

The first 16 bytes of the input value is the initialization vector to use when decrypting. The remainder is the encrypted data.

value - (byte[]) the value to decrypt encryption-key - (String) the key with which the value was encrypted

decrypt-as-str clj

(decrypt-as-str value encryption-key)

(decrypt-as-str value encryption-key charset)

Decryptes a value which has been encrypted via (encrypt) and attempts to construct the decrypted value into a string.

value - (byte[]) the value to decrypt encryption-key - (String) the key with which the value was encrypted (optional) charset - (Charset) decodes the array of bytes using a specified charset. if not specified uses the default charset

decrypt-from-base64 clj

(decrypt-from-base64 value encryption-key)

(decrypt-from-base64 value encryption-key charset)

Decryptes a value which has been encrypted via (encrypt-as-base64) and attempts to construct the decrypted value into a string.

value - (String) the value to decrypt encoded as a base64 string encryption-key - (String) the key with which the value was encrypted (optional) charset - (Charset) decodes the array of bytes using a specified charset. if not specified uses the default charset

encrypt clj

(encrypt value encryption-key)

Symmetrically encrypts value with encryption-key, such that it can be decrypted later with (decrypt).

Returns byte[]. The first 16 bytes of the returned value are the initialization vector. The remainder is the encrypted data.

value - (String/byte[]) the value to encrypt. Throws IllegalArgumentException if value is an invalid type. encryption-key - (String) the key with which to encrypt value with. Throws IllegalArgumentException if encryption-key is empty

encrypt-as-base64 clj

(encrypt-as-base64 value encryption-key)

(encrypt-as-base64 value encryption-key charset)

Symmetrically encrypts value with encryption-key, returning a base64 encoded string, such that it can be decrypted later with (decrypt-from-base64).

value - (String/byte[]) the value to encrypt. encryption-key - (String) the key with which to encrypt value with. (optional) charset - (Charset) decodes the array of bytes using a specified charset. if not specified uses the default charset
