Method takes a buffer with data encoded in Base64 format and decodes it into a new buffer.

If the input is not valid Base64 data, this method throws an error.

Base64 data is most often used for binary data encoding, so these functions are designed to work on buffer values.

If the data is stored in a string, buffer.fromstring can be used to quickly convert it into a buffer.

Method takes a buffer with binary data and encodes it using Base64.

Encoded result is returned as a new buffer.

Compresses the binary data stored in a buffer using the specified compression algorithm and compression level. The higher the compression level, the longer it takes to compress, but the resulting compression ratio might increase.

For CompressionAlgorithm.Zstd, the allowed compression values are from -7 to 22 inclusive.

Uses a cryptographic hash function to compute a hash of the input buffer. Returns a new buffer with the binary data.

See descriptions of HashAlgorithm to learn of the supported digest size for each hash.

Do not use this for passwords

None of these hashes are password hashing algorithms. They were designed to be fast to execute, whereas password hashing should never be fast. You shouldn't use this function for computing password hashes that will be stored, or for deriving keys from passwords.

Decompresses the binary data stored in a buffer using the specified compression algorithm.

Decompression might throw an error if the compressed data doesn't contain expected decompressed size, if it is larger than 1GB or if it is invalid.

It is recommended to use EncodingService.GetDecompressedBufferSize to find out the decompressed data size before attempting to decompress. This is very important if the input buffer contents are outside of your control (for example, from a client RemoveEvent)

Reports the size of the decompressed data stored in a compressed buffer. If the compressed data doesn't have a size or the size is corrupted or invalid (larger than 1GB), function returns nil. When a nil is returned, attempting to use EncodingService.DecompressBuffer on this buffer will throw an error.
