# Elliptic Curve 25519 The elliptic curve, Curve25519, was first released in 2005 by [Daniel J. Bernstein](https://en.wikipedia.org/wiki/Daniel_J._Bernstein). There has been some debate about when the curve was initially released because Satoshi's implementation was used in 2008, while the open source community didn't introduce it until 2013 in the [OpenSSH](https://en.wikipedia.org/wiki/OpenSSH) secure networking utilities. <span style="color: red;">(temporarily stubbed out)</span> ##### See Also > [Curve25519: high-speed elliptic-curve cryptography](https://cr.yp.to/ecdh.html) > [Curve25519 - Wikipedia](https://en.wikipedia.org/wiki/Curve25519) ##### Relevant Search Tags > #ec25519 #curve25519 #openssh #elliptic-curve-cryptography #cryptography
