israelid

A library to validate Israeli ID numbers.

Also available on JavaScript and Rust.

Usage

API reference

Validate an ID with ::israelid_valid_ascii:

bool israelid_valid_ascii(const char *id, uint8_t len);

Aligning the id to a 128 bit takes a faster code path.

Checksum

::israelid_valid_ascii is a convenience for:

• Checking len is the correct length (::ISRAELID_ID_LEN, i.e. 9).
• Calculate the checksum with ::israelid_checksum_ascii.
• Check the ::israelid_checksum_valid is valid.

Inverse

You can also compute which digit you need to add to an ID to make it valid with ::israelid_control_complement / ::israelid_control_complement_ascii.
