Functions 6

private fnint base64CharValue(char c) pure @safe nothrowReturns the 6-bit value for a valid Base64 character, or -1 if invalid.

private fnsize_t findStr(string haystack, string needle, size_t start = 0) pure @safe nothrowFinds the first occurrence of `needle` in `haystack` starting at `start`. Returns the index, or `size_t.max` if not found.

fnstring base64Encode(const(ubyte)[] data) pure @safeEncodes raw bytes to a Base64 string (RFC 4648).

fnubyte[] base64Decode(string encoded) @safeDecodes a Base64 string to raw bytes.

fnstring pemEncode(string label, const(ubyte)[] derData) @safeEncodes raw DER bytes into PEM format.

fnPemBlock pemDecode(string pem) @safeDecodes a PEM-encoded string into its label and DER bytes.
