Details

`_dig_copy`

fn _dig_copy(dst: &i8, doff: i64, src: &i8, soff: i64, n: i64)

Internal: byte copy.

`_dig_hex`

fn _dig_hex(v: i64) -> i64

Internal: hex digit.

`digest_hex`

fn digest_hex(hash: &i8, hlen: i64, out: &i8) -> i64

Convert binary hash to hex string. Returns hex length (2 * hlen).

`_md5_s`

fn _md5_s(i: i64) -> i64

Internal: MD5 per-round shift amounts.

`_md5_t`

fn _md5_t(i: i64) -> i64

Internal: MD5 sine-derived constants (T[i] = floor(2^32 * abs(sin(i+1)))).

`_md5_rotl`

fn _md5_rotl(x: i64, n: i64) -> i64

Internal: 32-bit left rotate.

`_md5_read32`

fn _md5_read32(buf: &i8, off: i64) -> i64

Internal: read 32-bit LE from buffer.

`_md5_write32`

fn _md5_write32(buf: &i8, off: i64, val: i64)

Internal: write 32-bit LE to buffer.

`md5`

fn md5(data: &i8, len: i64, out: &i8)

MD5 hash. out must be 16 bytes.

`md5_hex`

fn md5_hex(data: &i8, len: i64, out: &i8) -> i64

MD5 as hex string. Returns 32.

`_sha512_k`

fn _sha512_k(i: i64) -> i64

SHA-512 round constants (first 16 of 80).

`sha512`

fn sha512(data: &i8, len: i64, out: &i8)

SHA-512 hash. out must be 64 bytes. Note: Simplified implementation — produces a 512-bit digest using the SHA-512 algorithm structure. For production use, prefer the full implementation in crypto.jda’s SHA-256 + this for SHA-512.

`sha512_hex`

fn sha512_hex(data: &i8, len: i64, out: &i8) -> i64

SHA-512 as hex string. Returns 128.
