The original creation of Gpg4win was initiated and funded by Germany's Federal Office for Information Security (BSI) in 2005, [2] [3] resulting in the release of Gpg4win 1.0.0 on 6 April 2006; [4] however Gpg4win and all included tools are free and open source software, and it is typically the non-proprietary option for privacy recommended [5] [6] to Windows users.
GOST has a 64-bit block size and a key length of 256 bits. Its S-boxes can be secret, and they contain about 354 (log 2 (16! 8)) bits of secret information, so the effective key size can be increased to 610 bits; however, a chosen-key attack can recover the contents of the S-boxes in approximately 2 32 encryptions. [4] GOST is a Feistel network ...

It generates the header key and the secondary header key (XTS mode) using PBKDF2 with a 512-bit salt. By default they go through 200,000 to 500,000 iterations, depending on the underlying hash function used and whether it is system or non-system encryption. [14] The user can customize it to start as low as 2,048 and 16,000 respectively. [14]
In cryptography, key size or key length refers to the number of bits in a key used by a cryptographic algorithm (such as a cipher).. Key length defines the upper-bound on an algorithm's security (i.e. a logarithmic measure of the fastest known attack against an algorithm), because the security of all algorithms can be violated by brute-force attacks.
This table denotes, if a cryptography library provides the technical requisites for FIPS 140, and the status of their FIPS 140 certification (according to NIST's CMVP search, [27] modules in process list [28] and implementation under test list).

w – The length of a word in bits, typically 16, 32 or 64. Encryption is done in 2-word blocks. u = w/8 – The length of a word in bytes. b – The length of the key in bytes. K[] – The key, considered as an array of bytes (using 0-based indexing). c – The length of the key in words (or 1, if b = 0).
