## OID: `1.3.6.1.5.5.7.6.3`

```asn1
{iso(1) identified-organization(3) dod(6) internet(1) security(5) mechanisms(5) pkix(7) algorithms(6) id-alg-dh-sig-hmac-sha1(3)}
```

### Description

Static Diffie-Hellman Proof-Of-Possession (DH-POP) algorithm that uses SHA-1 as the Key Derivation Function (KDF) and HMAC-SHA1 as the Message Authentication Code (MAC) function

**Classification**: Algorithm, PKI (Public key infrastructure)

### Supplementary information

Defined in IETF [RFC 6955](https://www.rfc-editor.org/rfc/rfc6955.html).
Identifier `id-dhPop-static-sha1-hmac-sha1` was created for naming consistency with the other OIDs defined in [RFC 6955](https://tools.ietf.org/html/rfc6955). Identifier `id-alg-dhPop-static-sha1-hmac-sha1` is also listed in [RFC 7299](https://tools.ietf.org/html/rfc7299), section 3.11. Identifier `id-dh-sig-hmac-sha1` was defined in the previous version of the RFC, namely RFC 2875.
