Firebird Internals: Inside a Firebird DatabaseFragmented records store their data at offset 0x16. rhdf_f_page Four bytes, signed. Offset 0x10 (Padding bytes inserted). The page number on which the next fragment of this record can be found. Chapter next byte is repeated 'n' times, but stored only once. Zero if detected, end of data. Normally a padding byte. The data in a record is not compressed based on data found in a previously inserted record expanded, the data consists of three parts — a field header, the actual data and, if necessary, some padding bytes. Obviously, when decompressing the data, the decompression code needs to be able to know which0 码力 | 63 页 | 261.00 KB | 1 年前3
firebird 40 language referenceOtherwise, the result is a VARCHAR(endlen). • If padstr is given and equals '' (empty string), no padding takes place. • If endlen is less than the current string length, the string is truncated to endlen Otherwise, the result is a VARCHAR(endlen). • If padstr is given and equals '' (empty string), no padding takes place. • If endlen is less than the current string length, the string is truncated to endlen The hash used for OAEP padding; default is SHA256. RSA_DECRYPT decrypts encrypted_input using the RSA private key and then OAEP de-pads the resulting data. By default, OAEP padding is used. The PKCS_1_50 码力 | 778 页 | 3.43 MB | 1 年前3
