base64

An encoding method that converts binary data into ASCII text and vice versa. It is commonly used to send non-text files via the Internet's email system (see MIME). Base64 divides each set of three bytes of the original data into four 6-bit units, which it represents as four 7-bit ASCII characters. This typically increases the original file by about a third. See quoted printable encoding.

The first one is used as the entry in an address function, responsible for mapping keys (n-grams) to positions in the index table, using the k leading bits of the n-gram (since a digest of CTPH is Base64 encoded, it is necessary to decode it before selecting the bits).
Seen from the previous section, the cryptographic library can basically perform the following functions: Symmetric algorithm, Asymmetric algorithm, Hash algorithm, MAC (Message Authentication Code), HMAC (Hash-based Message Authentication Code), CMAC (Cipher-based Message Authentication Code), key Derive, SSL, TLS, PGP, cryptographic key management, certificate, random number, ASN.1, pem, BASE64 and PKCS (The Public-Key Cryptography Standards).
