Build

You can build the RPM / DEB packages for cryptint using pig build:

pig build pkg cryptint         # build RPM / DEB packages

Install

You can install cryptint directly. First, make sure the PGDG and PIGSTY repositories are added and enabled:

pig repo add pgsql -u          # Add repo and update cache

Install the extension using pig or apt/yum/dnf:

Install

pig install cryptint;          # Install for current active PG version

pig

pig ext install -y cryptint -v 18  # PG 18
pig ext install -y cryptint -v 17  # PG 17
pig ext install -y cryptint -v 16  # PG 16
pig ext install -y cryptint -v 15  # PG 15
pig ext install -y cryptint -v 14  # PG 14

dnf

dnf install -y cryptint_18       # PG 18
dnf install -y cryptint_17       # PG 17
dnf install -y cryptint_16       # PG 16
dnf install -y cryptint_15       # PG 15
dnf install -y cryptint_14       # PG 14

apt

apt install -y postgresql-18-cryptint   # PG 18
apt install -y postgresql-17-cryptint   # PG 17
apt install -y postgresql-16-cryptint   # PG 16
apt install -y postgresql-15-cryptint   # PG 15
apt install -y postgresql-14-cryptint   # PG 14

Create Extension:

CREATE EXTENSION cryptint;

Usage

cryptint: Encrypt and decrypt integers with SKIP32 and XTEA

SKIP32 (32-bit integer encryption)

Block cipher with 24 rounds based on Skipjack. Encrypts 32-bit values with an 80-bit (10-byte) key.

SELECT skip32_encrypt(42, '\x00010203040506070809'::bytea);
-- encrypted int4

SELECT skip32_decrypt(175586429, '\x00010203040506070809'::bytea);
-- 0

Roundtrip example:

SELECT i, skip32_encrypt(i, '\x00010203040506070809'::bytea) AS encrypted,
       skip32_decrypt(skip32_encrypt(i, '\x00010203040506070809'::bytea), '\x00010203040506070809'::bytea) AS decrypted
FROM generate_series(-3, 3) AS i;

XTEA (64-bit integer encryption)

Block cipher with 64 rounds. Encrypts 64-bit values with a 128-bit (16-byte) key.

SELECT xtea_encrypt(42::bigint, '\x000102030405060708090a0b0c0d0e0f'::bytea);
-- encrypted bigint

SELECT xtea_decrypt(103200416458222088::bigint, '\x000102030405060708090a0b0c0d0e0f'::bytea);
-- 1
