CSV, Crypto & Encoding

CSV

csv/parse

Parse a CSV string into a list of lists (rows of fields).

(csv/parse "a,b\n1,2\n3,4")
; => (("a" "b") ("1" "2") ("3" "4"))

csv/parse-maps

Parse a CSV string into a list of maps, using the first row as keys.

(csv/parse-maps "name,age\nAda,36\nBob,25")
; => ({:age "36" :name "Ada"} {:age "25" :name "Bob"})

csv/encode

Encode a list of lists into a CSV string.

(csv/encode '(("a" "b") ("1" "2")))
; => "a,b\n1,2\n"

UUID

uuid/v4

Generate a random UUID v4 string.

(uuid/v4)   ; => "550e8400-e29b-41d4-a716-446655440000" (varies)

Base64 Encoding

base64/encode

Encode a string to Base64.

(base64/encode "hello")   ; => "aGVsbG8="
(base64/encode "")        ; => ""

base64/decode

Decode a Base64 string.

(base64/decode "aGVsbG8=")   ; => "hello"

Hashing

hash/sha256

Compute the SHA-256 hash of a string. Returns a hex-encoded string.

(hash/sha256 "hello")   ; => "2cf24dba5fb0a30e26e83b2ac5b9e29e1b161e5c1fa7425e73043362938b9824"
