Encode a ShortByteString value as a Base32 Text value with padding.

See: RFC-4648 section 6

Examples:

>>> encodeBase32 "Sun"
"KN2W4==="

Encode a ShortByteString as a Base32 ShortByteString value with padding.

See: RFC-4648 section 6

Examples:

>>> encodeBase32' "Sun"
"KN2W4==="

Encode a ShortByteString value as Base32 Text without padding. Note that for Base32, padding is optional. If you call this function, you will simply be encoding as Base32 and stripping padding chars from the output.

See: RFC-4648 section 6

Examples:

>>> encodeBase32Unpadded "Sun"
"KN2W4"

Encode a ShortByteString value as Base32 without padding. Note that for Base32, padding is optional. If you call this function, you will simply be encoding as Base32 and stripping padding chars from the output.

See: RFC-4648 section 6

Examples:

>>> encodeBase32Unpadded' "Sun"
"KN2W4"

Decode an arbitrarily padded Base32 encoded ShortByteString value. If its length is not a multiple of 4, then padding chars will be added to fill out the input to a multiple of 4 for safe decoding as Base32-encoded values are optionally padded.

See: RFC-4648 section 6

Examples:

>>> decodeBase32 "KN2W4==="
Right "Sun"

>>> decodeBase32 "KN2W4"
Right "Sun"

>>> decodeBase32 "KN2W==="
Left "Base32-encoded bytestring has invalid padding"

Decode an unpadded Base32-encoded ShortByteString value. Input strings are required to be unpadded, and will undergo validation prior to decoding to confirm.

In general, unless unpadded Base32 is explicitly required, it is safer to call decodeBase32.

See: RFC-4648 section 6

Examples:

>>> decodeBase32Unpadded "KN2W4"
Right "Sun"

>>> decodeBase32Unpadded "KN2W4==="
Left "Base32-encoded bytestring has invalid padding"

Decode a padded Base32-encoded ShortByteString value. Input strings are required to be correctly padded, and will be validated prior to decoding to confirm.

In general, unless padded Base32 is explicitly required, it is safer to call decodeBase32.

See: RFC-4648 section 6

Examples:

>>> decodeBase32Padded "KN2W4==="
Right "Sun"

>>> decodeBase32Padded "KN2W4"
Left "Base32-encoded bytestring requires padding"

Tell whether a ShortByteString is Base32-encoded.

Examples:

>>> isBase32 "KN2W4"
True

>>> isBase32 "KN2W4==="
True

>>> isBase32 "KN2W4=="
False

Tell whether a ShortByteString is a valid Base32 format.

This will not tell you whether or not this is a correct Base32 representation, only that it conforms to the correct shape. To check whether it is a true Base32 encoded ShortByteString value, use isBase32.

Examples:

>>> isValidBase32 "KN2W4"
True

>>> isValidBase32 "KN2W4="
False

>>> isValidBase32 "KN2W4%"
False
