Please read some basic literature about applied cryptography.
Libgcrypt can't help you unless you have a basic knowledge.

@Book{Sch:96:AC,
author = "Bruce Schneier",
title = "Applied Cryptography",
language = "USenglish",
edition = "second",
publisher = pub-WIL,
address = pub-WIL:adr,
pages = "xxiii + 758",
year = "1996",
ISBN = "0-471-11709-9",
}

is good for an overview.

@Book{Men:96:HAC,
author = "Alfred J. Menezes and Paul van Oorschot and
Scott Vanstone",
title = "Handbook of Applied Cryptography",
language = "USenglish",
publisher = pub-CRC,
address = pub-CRC:adr,
pages = "xxvii + 780",
year = "1996",
ISBN = "0-8493-8523-7",
keywords = "cryptograpy",
}

Is what you need to read if you want to implement low-level stuff.

@Book{Fer:03:PC,
author = "Niels Ferguson and Bruce Schneier",
title = "Practical Cryptography",
language = "USenglish",
edition = "first",
publisher = pub-WIL,
address = pub-WIL:adr,
pages = "xx + 410",
year = "2003",
ISBN = "0-471-22357-3",
URL = "http://www.macfergus.com/pc/"
}

Is what you really need to read.

Shalom-Salam,

Werner
