You have to create a new buffer object and pass two parameters to its constructor. The SALT string is a user defined public key which will use for encryption and decryption data/string. Base64 encoders tend to break the result into lines typically of length 72 characters so if your Base64 encoder does this (and I bet it does) then you are almost certainly sendng the key as multiple lines BUT in the server you only read the first line and try to use that to reconstruct the key. This represents binary data in an ASCII strong format. December 29, 2013. To calculate the fingerprint, I extract the modulus and exponent from the public key, store them in another format (ssh-rsa) and calculate the MD5 hash.

Unsafe characters are in most cases replaced with hexadecimal codes (%). byteBuffer - a byte buffer to convert to Hex characters toDigits - the output alphabet (must be at least 16 characters) Returns: A char[] containing the appropriate characters from the alphabet For best results, this should be either upper- or lower-case hex. Your package would then begin with a "0" character (0x30 hex), followed by a header of 82 HH LL (where 0xHHLL is the length of the package - I get two less than binary key file length, even if I was expecting four less; you may want to check with a known good PEM base64-decoded sequence). The OpenSSH public key format¶ The public key saved by ssh-keygen is written in the so-called SSH-format, which is not a standard in the cryptography world. After this conversion, the RAW string is then encoded into its BASE64 form through the UTL_ENCODE.
