The settlement is located on the right bank of the Southern Bug, about 3 kilometres (1.9 mi) from the river.

History

In 1961, a construction of a big cement plant started. The settlement serving the plant was known as the Hrigorievka Cement Plant and belonged to Varvarivka Raion of Mykolaiv Oblast. In 1963, Varvarivka Raion was abolished and Mykolaiv Raion was established.[2] In 1968, Hrigorievka Cement Plant was renamed Olshanske, to commemorate Konstantin Olshansky, a Hero of the Soviet Union, and it was granted urban-type settlement status.[2][3]

Economy

The settlement serves a cement plant which belonged to Dyckerhoff AG.[2]

Transportation

There is a railway station in Olshanske on the railway line connecting Mykolaiv and Kudriavtsivka, with further connections to Odessa and Voznesensk.

gollark: So this is a mess. PotatOS is actually shipping a mildly different ECC library with a different curve because steamport provided the ECC code ages ago.
gollark: I mean, what do you expect to happen if you do something unsupported and which creates increasingly large problems each time you do it?
gollark: <@151391317740486657> Do you know what "unsupported" means? PotatOS is not designed to be used this way.
gollark: Specifically, 22 bytes for the private key and 21 for the public key on ccecc.py and 25 and 32 on the actual ingame one.
gollark: <@!206233133228490752> Sorry to bother you, but keypairs generated by `ccecc.py` and the ECC library in use in potatOS appear to have different-length private and public keys, which is a problem.EDIT: okay, apparently it's because I've been accidentally using a *different* ECC thing from SMT or something, and it has these parameters instead:```---- Elliptic Curve Arithmetic---- About the Curve Itself-- Field Size: 192 bits-- Field Modulus (p): 65533 * 2^176 + 3-- Equation: x^2 + y^2 = 1 + 108 * x^2 * y^2-- Parameters: Edwards Curve with c = 1, and d = 108-- Curve Order (n): 4 * 1569203598118192102418711808268118358122924911136798015831-- Cofactor (h): 4-- Generator Order (q): 1569203598118192102418711808268118358122924911136798015831---- About the Curve's Security-- Current best attack security: 94.822 bits (Pollard's Rho)-- Rho Security: log2(0.884 * sqrt(q)) = 94.822-- Transfer Security? Yes: p ~= q; k > 20-- Field Discriminant Security? Yes: t = 67602300638727286331433024168; s = 2^2; |D| = 5134296629560551493299993292204775496868940529592107064435 > 2^100-- Rigidity? A little, the parameters are somewhat small.-- XZ/YZ Ladder Security? No: Single coordinate ladders are insecure, so they can't be used.-- Small Subgroup Security? Yes: Secret keys are calculated modulo 4q.-- Invalid Curve Security? Yes: Any point to be multiplied is checked beforehand.-- Invalid Curve Twist Security? No: The curve is not protected against single coordinate ladder attacks, so don't use them.-- Completeness? Yes: The curve is an Edwards Curve with non-square d and square a, so the curve is complete.-- Indistinguishability? No: The curve does not support indistinguishability maps.```so I might just have to ship *two* versions to keep compatibility with old signatures.
