getrawtransaction asm returns with [ALL], should it be?

0

.\bitcoin-cli.exe getrawtransaction af66f73a42d33a446e52f1c8e82a99fcd9d788a0ec5c70de6f633
213a7546cdb true

"scriptSig": {"asm": "30460221009c8...acc0a2a [ALL]

the same transaction on blockchain

ScriptSig[30460221009c82db110da31acc0a2a01

Why different line endings?

cc0a2a[ALL] and cc0a2a01

A through blockchain-decode-tx returns the cc0a2a0121

The representation of data is from site to site different. The hexcode "01" is a SIGHASH ALL Opcode, defined here.

I show here all the opcodes and their definition of your example. Basically sigscript of this example consists of . The signature is an ASN1 DER structure, followed by the public key as hex chars. Drilling deeper, it gets this: 

49: OP_DATA_0x49:        push hex 49 (decimal 73) bytes on stack
30: OP_SEQUENCE_0x30:    type tag indicating SEQUENCE, begin sigscript
46: OP_LENGTH_0x46:      length of R + S
02: OP_INT_0x02:         type tag INTEGER indicating length
21: OP_LENGTH_0x21:      this is SIG R (33 Bytes)
02: OP_INT_0x02:         type tag INTEGER indicating length
21: OP_LENGTH_0x21:      this is SIG S (33 Bytes)
01: OP_SIGHASHALL:       this terminates the ECDSA signature (ASN1-DER structure)
21: OP_DATA_0x21:        length compressed Public Key (X9.63 form, 33 Bytes)

So [ALL] and "01" indicate the same. One format is showing the OpCodes (see also in the scriptPubKey section), one is plain hex representation, to make cut&paste easy. All opcodes are here.

1It's strange to prefix all those things with "OP_". They're not opcodes; just part of the DER serialization. And the sighash ALL flag is appended by Bitcoin to the ECDSA signature; it's not part of it, and certainly not DER encoded. – Pieter Wuille – 2018-03-17T00:11:39.913

yup, sure. Got that, no Op_Codes, maybe operators, or TT for type tags. In the ASN1 specs they talk a lot about byte values, maybe BV instead. – pebwindkraft – 2018-03-17T11:42:52.063
